IMHO our innovators should be focusing on improving public transport. This is why I prefer that people live in cities rather than suburbs. You can go around without having to use your car. In the better designed cities, it's even possible to just ride a bike or walk to work.
Totally agree! American city planning is full shit, suburbs waste a lot of energy and people spend many hours in traffic jams. You must learn from Europe how to build good cities!
On one side of the tube is the problem, on the other hand, the presence of the tubes talks about the good welfare of the citizens. It means everyone has the money for the purchase and maintenance of vehicles.
