I drive 72 in a 65 and 77 in a 70. Many folks drive 5-10 miles an hour under the speed limit. On our drive back from Florida, I noticed most of these folks are older (60s & 70s). I do not believe these people cannot see or feel uncomfortable behind the wheel. They just seem to be living at a slower pace, never in a rush. Do they know something I don’t? Or will I be 75 years old driving 77 in a 70?
