Comment on Tesla reintroduces 'Mad Max' Full Self-Driving mode that breaks speed limits
Semi_Hemi_Demigod@lemmy.world 5 months agoIt’s not speed that kills. It’s acceleration. Everyone doing 70 means nobody is an obstacle. But one person doing 55 in that situation is effectively a rolling road block. Even if they’re not hit by someone else they’ll cause accidents as people change lanes to get around them.
“It’s not the speed that kills”
Yes it is. It’s the speed and the weight.
The impact force doubles from 55 to 70. That’s a spectacular difference. Driving cars is already the most dangerous thing we do and this talk about if computers make good judgment calls or not? They make better judgment calls than humans every time.
Just because people want to speed on the road doesn’t mean we need to accept the crazy idea that it’s somehow safe for them.
Yes but if everyone is doing 70 there won’t be impacts between the cars.
Obviously any road where people are doing 55 shouldn’t have pedestrians or cyclists.
Acceleration is a derivative of velocity
Which is also a vector. Speed is a scalar.
This is complete bullshit, by someone who has an idea but knows nothing.
At 70 break distance is longer, time to react is shorter, and collision speeds are higher. All factors that increase danger and damage.
You might as well claim that driving 250 is perfectly safe if everybody do it.
If everyone is doing 250 they won’t hit each other. But if one person is doing 125 things get a lot less safe.
The rest of it is not what I’m talking about. I am aware that all of the rest is true, but is outside of what I’m describing.
Maybe we just eliminate all transportation that can exceed walking speed. You know, for safety.
Sorry for the second reply but these kinda arguments always remind me of the joke
“No street racing should be legal. It’s completely safe! Oh not if they crash but that’s street crashing not racing. I’m very against street crashing. Racing is safe tho”
I know a few people who have been pulled over for driving the speed limit and making it unsafe by creating a rolling road block.
Most accidents on highways are the result of lane changes, and people not going with the flow of traffic increases lane changes.
“Between cars”
Right it’s not like anyone ever has car trouble and the road is always free of obstacles and animals!
It’s exactly like the oil pipeline people. “It’s perfectly safe unless it leaks” but they always leak!! That’s just a fact of life!
“Any road where people are doing 55 shouldn’t have pedestrians on cyclists “
Lots of roads are 55 and have sidewalks.
Hell I got a perfect example. I know one road near the airport that’s 60 until about 100 yards from the school zone where it drops to 20 then picks back up. No one slows down. They blast 70 straight thru (people add 10mph to every posted sign around here because the cops “won’t pull you over for just going a little over”)
So my question to you… on that road what is the safe solution? Should cars slow down and risk a wreck that way? Blast thru the school crosswalk going 70? Or do we need to just close the school and move it away from all those important drivers in a hurry?
Go the speed limit. Safety laws are written in blood buddy. They exist because people kept dying.
Bad road design is an entirely different problem.
And I’ve got a question for you: it’s rush hour and everyone is doing 70 in a 55. How do you enforce this? Pull everyone over?

The evidence is very clear that speed kills. You are spreading misinformation.
Semi_Hemi_Demigod@lemmy.world 5 months ago
A car doing 70 will not hit another car also doing 70.
Whether they hit something else is a different situation.
But a car doing 55 in traffic doing 70 is a -15mph roadblock that will either be hit by someone else or cause an accident as people change lanes to get around it.
Unless you’re able to stop everyone from speeding it’s going to be this way.
