Now that we have electric and self-driving cars you assumptions of what a car is have the ability to be drastically altered.
>Space? Roads take up way more space than tracks.
Highways can now be minimised to two tracks, the standard width of a vehicle, vibration reports can tell the councils where pothole repair is most needed.
>Moving a 2000kg electric car around for 1 person is never going to be efficient.
Car's are 2000kg in part to protect the driver, as crashes trend to 0 there's no reason they need to be so big.
>Roads even with autonomous cars will never have the throughput of a train-line.
Trains are rarely full. Cars can get smaller, we can mitigate traffic jams.
A single lane of highway doesn't get more than 2000 cars per hour. Even self driving won't increase that much. If all cars have to wait for someone to get out of their cars since we're only on 1 lane then it'll get even worse.
Eletrics cars are 2000kg because a the battery weighs a lot.
Trains get smaller too when it's not rush hour. France regularly runs one carriage trains the size of a bus.
Mitigate and smooth flowing aren't the same thing. On way to work I see cars backed up for miles. Doesn't matter if they're self driving or not when cars move bumper to bumper already.
