Last drove a RHD bus about 20yrs ago, my '67 split Devon. A bus is so different to a conventional car to drive, that now used to LHD Bay, anything else would seem wrong! I have clipped door mirrors and kerbs in the car after driving the bus, too much sticking out on the left!
The only hassle for me so far was going to Vanfest. Joining motorways or changing lanes in the dark with torrential rain was like Russian roulette, but we survived and am aclimatising (sp) to the whole mirror thing!. Would not change things for the world. I love my bus as it is, it just feels 'right'!
