Make it compulsory for MPs and city Mayors to travel daily by public transport.

There has rarely been a time when there was more distrust between the governed and the governing. We can't all share a working environment, but we can share our mode of travel to work. The disconnect between the world-view of constituents and that of politicians, would be vastly reduced if politicians experienced the reality of the towns and cities their constituents live in as their constituents experience it, and see the people and events they encounter, during their daily commute.
