On my commute into Edinburgh of a morning I notice that each car only has one person in it.
This is a terrible waste of space.
If cars were shortened to reflect the redundant space then the flow of traffic would improve tremendously.
I am crowd funding to create The Crusher. This will be a mostly harmless device which will shorten cars to say 3 metres. Obviously this could be adapted for example if your car was very long and you were also an ignorant driver giving scant regard to other road users (bikers, cyclists, scooters, pedestrians Etc) a simple twist of the dial could extend the crushing period and bring your car down to 2.5 metres.
Clearly if people were willing to car share The Crusher would be unnecessary. Sadly given The Situation we live in, with the world all Swift and Angular and anomie raging everywhere it turns out everyone must have their own car. So shorter cars is the clear solution. I also would suggest that bringing in a congestion charge linked to vehicle length is another winner. Cars of 2.5 metres or less need not pay the charge. For example.
Bring on The Crusher.
