I never said it was for everyone but since you mentioned it, public transport where I live very rarely smells but I will agree that it can get too cold under some of the air con vents and having visited New York recently (I'm assuming you're American, apologies if you aren't) I totally understand not wanting to partake in the stank lottery.

Also, you don't have a pair of headphones? :P

As a tall person, I can't drive more than 30 minutes without needing a break for my legs. Stop-and-go traffic is especially hellish because I have to keep my feet on the brakes the whole time. Not a pleasant experience by any means.

Some manufacturers solved this problem as well - in my car(Mercedes) you can tap the brake with your foot when stopped and the car will hold the brakes until you press the accelerator again. So in stop and go traffic you don't have to keep your feet on the brakes. But yeah, I can see being uncomfortable as an issue.

Try doing it with a manual transmission.
