Of all the vehicles in the London traffic, I find the Famous double decker bus to be the most annoying. I have no logical reason for this, it doesn't appear to be any slower on its "feet" than the normal size buses. It's not wider or longer than them, actually the "benda" buses are way longer and they don't tickle my temper the way a the double deckers do. The only difference really is the height of the bus and it's not like I would be able to drive over the top of the bus anyway, not until I have got a "hover-conversion" applied to the the car.
Ah well, another one for the psychiatrist.
