> Semi drivers have this even worse.

There are some advantages to driving a semi in traffic:

- Lots of gears to choose from and massive torque in order to find that perfect 'idle forward' speed.

- Far more comfortable ride then a car, it's not even close.

- Radio communication with trucks ahead, so you know what's happening ahead and which lane to be in long before the cars figure this out.

- Visibility over the top of vehicles in front (except another truck, obviously).

I think the only thing better than a semi for heavy traffic might be a luxury car with adaptive cruise and a little roof-mounted drone-cam that you could launch to check out the view ahead (though this sounds like something Homer Simpson would dream up). Your own little personal traffic copter/R2D2, with a recharging dock on the roof. Someone please tell Elon Musk to make this a priority for new Teslas. It could even check out side streets in cities and find quicker routes.

I was thinking stop-and-go traffic, which is murder.

Heavy load = longer stop distance = lengthier minimum safe following distance

Minimum safe following distance > 1 car length = motorists darting in front of semis

Rinse and repeat. Assuming a heavy load and ignorant motorists, there's no way to avoid constant unsafe situations. As soon as you create a new safe gap, someone slides in.

So, no. It's terrible. (And I'm not even mentioning the additional gear shifts)
