The problem with bikes is that you get incredibly sweaty even in the winter. I'm sure there's solutions to that as well but I would prefer not to have to towel down or change clothes after arriving at my destination.
Maybe it's just because I bike a lot, but during the winter, I don't get sweaty at all. I used to be able to bike 95% of the way to work (2.5mi) in jeans without getting sweaty until late June or July. (Those last two blocks going uphill would usually get me, sadly.)
And this is in Austin. Yeah, right now I'll get sweaty, because we hit 107f heat index every other day. During the winter I can bike ten+ miles in jeans and a t-shirt without getting sweaty.
I can see this being useful in France. I was basically accused several times of being shoplifter. At one store they demanded to look inside my bag and then zip-tied it shut. At another store they wanted to go through my bag at checkout. It was all very rude and undignified.
