Given how many people treat speed limits as suggestions, at best, having your vehicle obey the limit would turn some people off of them.
Truly self driving cars would allow you to participate in other activities safely while the car moves you. You could read a book, play a game, apply your makeup, etc. Given that trade-off, I think most people would be willing to sacrifice the extra 2.5 minutes a trip.
2.5 minute estimate derived from the difference of travel time between half the average US daily travel of 42 miles at a speed of 60mph and the same distance traveled at 68mph.
Most people would accept the trade-off of being in the car 5 minutes longer per day if it meant they got 42 minutes of leisure instead of 37 minutes of weaving through traffic.
Also with a critical mass adoption of self-driving cars the speed limit could be increased.
Also with a critical mass adoption of self-driving cars the speed limit could be increased.
Only if the bicycle paths are separated from the road by a wall.
If there was 100% adoption of self-driving vehicles with a inter-vehicle communication network, there is no reason why the left lane couldn’t go 100+ mph. There still would be lower speeds outside of the highway, but they could be substantially higher than today on most major roads.
Human drivers are why speed limits exist. People follow too close, people are impatient, people are aggressive, people are risky, people don’t know what the vehicles in front of them are going to do, people don’t use turn signals, people hit the brakes and cut across multiple lanes of traffic because they weren’t paying attention or missed their exit, etc.
Networked autonomous cars can communicate and collaborate, allowing for faster and safer travel. The left lane could have no speed limit because every car using it, leaving it, or entering it are all in agreement on what needs to be done and what to do and when to do it. Cars on major roads would slow down so another car can turn without causing the cars behind it to stop. Oncoming cars could slow to allow for an opening that a turning car can use instead of waiting for an opening in irregular traffic, or taking a risky turn that causes an accident.
Getting to that system will require laws against manual driving and mandating that all new vehicles have full autonomous driving. I hope I am dead before that happens because that future sounds awful to me.
The major roads are already nigh impossible to walk across. Finding a way to raise the speed just makes it harder to be a pedestrian in yet more places.
I, too, love the idea of networked autonomous swarm agents behaving in an even more efficient setup. The problem is that if the only focus is on moving cars faster at the cost of people’s comfort, access, energy, and walkable anything we lose out on reasons to ever be outside of the car at all.
More cars and faster cars in our cities makes the city worse, even if they’re self driving.
I’ll echo that there are safety issues. Motorcyclists (I ride my much more fuel-efficient bike when I don’t have something too big where I need my car), bicycles (which I also ride for leisure and errands close by), and pedestrians (same here) aren’t going to work very well in that. You’re not going to mandate that every person carry some kind of transponder and that it must always work. Where I live, many students are walking and cycling. I also think tractors, dump trunks, and other special equipment will still have human drivers for at least part of the journey for the foreseeable future.
Also, smacking into an animal at 160kph is terribly dangerous and potentially damaging. A blowout at that speed also has much scarier implications for control. A lot of hazards would need to have issues solved here as well.
I don’t think the people who want to speed are the kind of people I want driving anyway.
Admitting you want to bypass the rules should be a red flag and imo warrant an immediate cancellation of your permit. You’re driving a thousand kilos of metal at bone shattering speeds, if you can’t be trusted to be responsible, don’t drive. (And it’s a general you, not you OP)
Does it bother you if the driver is driving slowly when you’re a passenger though? I don’t think most people will care that much if thier self driving car follows the speed limit.
This is true, but I think the bigger deal is that some people actually like driving (maybe not the trafficky daily commute). Some speeders fit this category, but also others who just like being precise on the curves, being in the flow of an uncrowded road, and even expressing their neighborliness to others.
So far, self driving cars drive very clumsily even when they are safe. More scope for embarrassment and frustration than anything else if you identify with the behavior of your car. “Chill mode” for example, chooses the right of a four lane road until the last minute instead of making lane changes when space allows. Awful.
But even if the cars get better at it, some people will miss driving.
If you think that’s a satisfactory replacement for the average person you don’t know much about motorsports. The costs alone are outside the reach of most people.
I’m not one to advocate for cars of any kind, but I sure don’t care about the particular speed when I’m lost in the sauce listening to music or reading on the train
