mrgreen - I seem to recall the bell being mandatory in Germany, too, from my time there.. although it's a while back now and my memory is foggy!
I've considered cycling to work, too - it's only 12 miles across country (via mostly 40-limit roads aside from the lovely twisty NSL section that I'm inevitably stuck behind someone doing 40 down
).. aside from the fact that I'd only get about 500 yards before having a coronary and I doubt there's a bike out there designed to support my weight 
Wait.. that's probably not a laughing matter, is it 
Same here. Last time I got my bike out I cycled about half a mile up the road for a pint of milk (OK, there was a big hill in the way). Came out of the shop and downed the pint of milk in one. Had to go back in for another one. 
Long way to go before I can do the 20 miles to work.
The added bonus of living at the highest settlement in Hampshire means there's always a 200 foot climb to finish me off at the end should I survive the rest of the ride.
No, my bike is quite happy hanging up in the garage.

That's where mine was, too, until I moved house (it'd hung there for 10 years and I've owned the bike since I was 15!

) .. now I think it's in the boot of the Nissan, at least I think that's where it got stuffed during the house move

I'm amazed it's not a pile of rust by now.
Although I thought about it the other day - the last section before work would all be downhill for me, and ditto the last section before home on the way back, so it would work out quite nicely.. if I could make it that far

I suppose I
could find a bike that could take my weight (all, er, 160Kg roughly I guess!) - but I suffer from vanity.. and enormous blokes on bikes look a bit.. daft, no..
