Hey Oppo!

I have a question which, I am sure, many of you have an opinion.

I drive about one mile to and from work every day (for a total of almost two miles!).

About once or twice a week, I drive 30 miles continuously at up to 80 mph.

How much damage do you think I'm doing by my short work commute trips?

Thanks for all your advice. Here's a Super20 for your efforts.
