Could the UK drive on the right?

I've driven in England, it takes me about 20 minutes to really get 'in' to it, after that it is ok. The danger points occur when you enter traffic from a very small road onto a larger one and there is no other traffic. Years of conditioning are hard to overcome when there are no other references.
And when crossing the street, I invariably look the wrong way. Nearly got flattened by a bus outside a London convention center a while ago. Good brakes on those buses!
Amazingly, if you watch pedestrians they will either avoid oncoming pedestrians left or right depending on their country's of origin driving direction! Try and observe it when you next in Heathrow!
Switching from one side of the road to another when visiting continental countries is a trivial problem easily encapsulated by the process of crossing the channel. I regularly move between the UK and France and happily drive cars on either side of the road and with the steering wheel on either the left or right depending upon which car I am driving.
