I'd like the public transport to be viable replacement to cars ...
... however it is just a wish. What with signal failures occurring everyday on the tube, the air quality on platforms worse than middle of a very busy road, and buses running to some unimaginable and very unreal schedule. If tube was fixed and buses replaced by, say, level 5 autonomic public transport electric cars at the 10% of a price of a regular cab, that would be most useful. And this not happen for a very very long time, because unfortunately anyone in position to push such change will be beholden to transport unions.
