Our nice, bland, old fogeymobile Camry feels just the same at 90 as at 60. I'm glad it has cruise control, as my foot does get too heavy too easily. I usually have it set at 5mph over, and leave the right lane only to pass aging turtles.

Last summer we drove the furthest we have in Canada, from Maine to Nova Scotia and across Canada back to Michigan. We saw signs everywhere emphasizing how seriously we should take the speed limits. Then we stayed overnight in Toronto, and the hotel supplied a newspaper. There was a long scathing editiorial attacking people who
don't drive well over the posted limited, with a little extra dose of vitriol for anyone who would dare drive a kph under.
