Like Doki, Steve and Timo, I don't think sitting in traffic jams is a good use of your life. Apart from the obvious answer to your problem, which is "I wouldn't start from there", I have to say a motorbike does seem a remarkably sensible option if it's too long for pedalling and there's no suitable PT. S'pose part of it is how much do you trust yourself not to be really yobby on a bike - coz I'm guessing that's a bad idea for a regular commute.
Question is, are you strapped for cash, or can you afford to spend a little to free up quite a lot of time every day? It does seem like there's quite a good payoff there. Then you keep the barge for fun.
(and yes, I'd be looking for something boringly economical for a bike - reliable, rather than odd).
cheers, clive
