Is human reaction time is the only reason for enforcing safe driving distance?
Even if AI increases to great levels, inertia still would exist. A large truck cannot stop in inches when traveling at 100 mph.

- John_KZ 9y agoBut the truck in front busted a tire... Now what? If the distance between vehicles is 1cm,then literally thousands of vehicles will crash. The AVs could offer some advantages (ie cheap car sharing via resource pooling, reduced parking space requirements in urban centers) but safety or speed aren't part of the deal. AI isn't superhuman and AVs aren't able to brake the rules of physics.
- CPLX 9y agoAn interesting thing about objects is that they can move in three dimensions. All you need is an object of any kind, including a downed tree limb or falling rock, entering the stream of vehicles at an angle, to cause cataclysmic disaster in this scenario.
- sn41 9y agowhat if the vehicle in front is a small car?
- ygra 9y agoHuman reaction time would be a reason for additional distance beyond what is needed to stop, but agreed, I don't see the distance to be reduced that much. Reducing the distance to virtually nil is going to cause a crash at the first slope as well.
