Aluminium-based antiperspirants work for days between re-use if anyone is worried about sweating (and yeah, according to studies it is not as unhealthy as people think it is, at least not in those amounts, and no one told you to bathe in it).

Not being exposed to rain... well... I dunno, I live in Europe and people just dress up as needed. Mostly it is just a matter of using an umbrella anyways.

Or go to the bathroom, change tshirt, use some deo and you're set for the day, it really isn't rocket science. You're exercising, saving hundreds of kilos of co2 per year, and saving 10+ sqmeter of parking space. Not to mention no gas, no insurance, virtually no maintenance.

Sure, there are many alternatives. I prefer the antiperspirant way, because I hate sweating a lot, and I would rather not wash clothes more regularly, but to each their own. It is still car-less. :)
