Ok this is a little obscure but here goes. You have ten cars all fresh out of the manufacturer. All with the same mileage, for all intents and purposed they are all exactly the same. You line them up one behind the other, each exactly 1 foot behind the one in front. Each driver is instructed on a mark, to hit the gas at the same time. Like 3, 2, 1 gas.
Let’s say they all hit the mark spot on at the same instant and keep the exact same pressure on the gas for say 1 mile…
Would you have a huge pile-up? or could it be done with out anyone getting hit from behind?
This is just a WAG, but since your question is in IMHO and not GQ, I guess that’s allowed. I think you’d eventually have a collision. The front car is going to have to work a bit harder than the one behind it, since the second car benefits from being able to draft behind the first. I don’t know if a mile would be enough time to notice the difference or not, but I think car 1 would end up getting bumped.
In a nutshell, it wouldn’t work. Manufacturing tolerances aren’t that close. Driver reaction times aren’t that good. There’d be inconsistencies in the traction between tires and road at different locations. The weight of the drivers would affect acceleration.
If you removed the constraint about having the exact same pressure on the gas and allowed for computerized control, you might get away with it.
