What if you could do 100mph with perfect congestion control in the e-lane?
Just imagine a world where rush hour didn't mean slowdowns. Oh and also get rid of the onramp metering; it's worse than useless when traffic can't zipper and accommodate the influx of new vehicles.
The rulemakers would allow your car to drive at a MUCH higher speed than allowed by "human" driving.
and it would maintain the speed.
The cars would perfectly merge in and out, maybe including perfect metering or buffering of cars exiting.
They would drive at a specific distance from each other and speed up and slow down synchronously.
oh, and don't charge for it.
If you want to own one for exclusive personal use, you'll be doing so in an environment that's increasingly unsympathetic to your needs as somebody with a fleet size of one and a customer base of one.
