I first learned how to drive on these old pickup trucks at a summer camp I worked for as a teenager.

The nice old fella who maintained the trucks (and who, not incidentally, taught me how to drive) said to do it that way and would get disappointed if you didn’t.

So, I guess it’s because I first learned it that way, but also because I don’t want to disappoint Alan (who may or may not be dead by now, I’m not sure.)
