The law says, regardless of the speed limit, you need to be driving slow enough to react to someone suddenly stepping on the road. If you can't do that while driving at the speed limit, you'll just have to drive slower.
- The law says, regardless of the speed limit, you need to be driving slow enough to react to someone suddenly stepping on the road. If you can’t do that while driving at the speed limit, you’ll just have to drive slower.
  Taken literally, that means that since you won't be able to stop if someone steps just in front of your vehicle, you should never drive faster than ~10kmph. Which can be a valid interpretation, but I doubt it's going to be a widely accepted one. For example at least where I live, if someone steps in front a vehicle within breaking distance driving at the speed of the road's legal limit, both pedestrian and driver will share responsibility (the exact ratios being determined by the exact situation).
  
  If you actually think about it, it's absolutely makes sense. The Autobahn has additional stopping lanes for broken down cars and several meters of grass to each side, which means you can safely drive hundreds of kilometers an hour while still being able to see obstructions early enough to brake in time.
  Slower motorways have smaller setbacks, but still enough to keep their speeds.
  City streets where you can't see people entering the road in time to brake usually have relatively low speed limits to reduce the braking distance as well as the damage caused by a collision.
  But if the visibility or braking distance are affected due to weather or broken streetlamps, it's up to you to slow down accordingly. But even for situations like that traffic planners usually add additional signs, it's common to see roads with signs that say
  
  /❄️\ (60)
  to warn people to drive slower when the road is freezing or signs that say
  
  /🦌\ (50) [400m]
  to warn of crossing animals in the next 400m and set a lower speed limit.
  The same obviously applies when it's not crossing deer but crossing pedestrians.
- Not how that shit works. At all.
  First, throwing out generic legal advice is dumb. It's not consistent in any way. Second, in most states and countries you'd have to prove negligence. You absolutely will not and should not be held responsible if some idiot runs out between two cars and gets hit while you are following the law.
  
  Actually, in EU countries the law explicitly says you have to drive slow enough to react to unexpected changes on the road. If you as a driver hit something or someone, you are automatically at fault because you violated that law. There is an incredibly high burden of proof required to not be at fault as a driver.
  But that's usually not an issue, because road planners are only allowed to set speed limits that are low enough that drivers can actually react to unexpected changes. Which is why e.g. the Autobahn has a separate lane for broken down vehicles and significant setbacks and green areas to both sides of the road so you can see from a long distance away if something is in the road.
  
  👌👍
- Ah. So you don't have a magic secret but will still smugly pretend you do.
  That seems safe
  
  Slow. Down. That's all there is to it.
  
  I guess people angrily speeding past and honking means they would hit the ninjas, so.. kudos.
  Unless they just get angry and blast high beams into my rear mirrors even more.
  Don't disrupt the flow of traffic
  
  The speed limit isn't a suggested speed, it's an absolute maximum (excluding motorways with a minimum of 60km/h). If the road is frozen over you can't drive the speed limit either, the same applies when it's slippery due to rain or leaves or when the lights are off.
  You always need to be able to react to sudden movement, no matter if it's a pedestrian crossing the street, a motorist leaving their own driveway or even a trash can rolling into the road. It should be in your own best interest to avoid accidents.
  The entitled attitude you ascribe to the overtaking drivers but also display yourself is just going to cause problems for everyone. Trying to shave a few seconds off of your commute by speeding in dark areas isn't going to get you home any faster, all you're doing is increasing your own stress level and risking someone's life.
  A little bit of respect on the road would go a long way to improve everyone's experience on the road.
  
  Ignoring the massive disruption that going below the speed limit causes and the increased aggression it instills in other drivers who understand how to follow the rules of the road:
  A sedan is, on average, 1302 kg according to a random quora page. 45 miles per hour is approximately 20.116 meters per second. So about 26.191 newton seconds. People aren't surviving that.
  So unless you are battling entitlement by going thirty miles under the speed limit (which will probably still squish a person but I am too lazy to math it), all you are doing is antagonizing everyone around you while filling yourself with a false sense of security.
  Seriously, and I mean this from the bottom of my heart, take a defensive driving course. Defensive driving is about learning to anticipate the drivers around you and how to minimize the chance of a collision. Which is not the law you learned in driver's Ed. It makes you a much safer driver and will probably lower your insurance premium.
  That means driving in a way that doesn't anger everyone around you and knowing when you actually need to slow down and when doing so won't help
  
  First off, city streets are by law limited to 50km/h (30mph) in Germany unless the road is physically blocked off from pedestrian access and is designated a motorway. And even that speed is only allowed for major thoroughfares, most city streets are limited to 30km/h (18mph), and many cities are currently arguing for banning 50km/h on city streets entirely.
  Streets faster than that need to be physically separated, well-lit, need to have an additional lane or frequent additional locations to park broken down vehicles and need significant setbacks so you can see potential obstructions entering the road early enough to brake in time.
  So what I'm taking from this is that the road design where you live is dangerous and substandard.
  Now, to the personal appeal:
  I did take a defensive driving course before I even started driver's ed, and it was actually the reason I decided not to get a car. Nowadays I do everything — including weekly grocery runs — by bicycle instead.
  The average speed in cities is 15-20km/h, primarily caused due to traffic jams and waiting times at stoplights. I can achieve or beat those speeds on a bicycle just as well, without the stakes being as high. If I make a mistake as a driver, it's going to cost lives. If I make a mistake as a bicyclist, no one's going to die. And considering the environmental footprint as well as the monetary costs in terms of road tax, fuel prices and maintenance, it's definitely worth it.
  Even if sometimes, people try to kill me by overtaking me far too close while speeding.
  
  Ah. So you are uneducated, inexperienced, and live in a completely different environment but will still insist you are correct.
  Is there an American milkman anywhere nearby? Because he totally knocked your Mom up. Like, I know people who traced their ancestry back to the American revolutionary war who are less American than you
  
  "completely different environment", ah, since when is Lemmy US-only?
  
  This is a topic about safety features being considered for us cars because of us conditions.
  I would make a snide comment about reading comprehension but I genuinely am concerned for you at this point.
