I don't drive my '40 everyday, but close. It gets as good or better gas mileage than my late model truck and is way more fun to drive. I put almost 6K miles on it this year (basically early spring til now). I know that is not a huge number of miles compared to some guys, but does show that I am not afraid to drive it. In a way, I wish I would have left it stock height. It didn't look as cool (in my opinion) but it was far easier to drive.
Even trying to be careful, I always feel like my cars go downhill fast driving them regularly. It's just something I have to get over. Cars were meant to be driven and not just sit and gather dust in the garage.
I give this guy credit for going all out 365/7 days a week in a Model A. Inspires me to not only drive more, but keep some sort of journal about experiences. One day someone will care. ...well, hopefully anyway...
