Looking at this from a different perspective, there are 8,760 hours in a year. If you drove less than 8,760 miles last season, then you averaged less than one MPH for the year.
I agree with luckyal. 30-35 is good for me as I am enjoying the scenery and drive my A for the fun of waving to folks and having the ride last longer. I also grew up with antiques in a Model T and a bit of that still is with me.
