Agreed. Even my daily driver from the 80's would get along just fine in today's traffic. Acceleration hasn't been a problem since 1980 unless you were driving something by Wartburg or so.
My family's Pontiac 6000 had a 2.5 liter 92 hp pile of hot garbage for an engine, and couldn't get out its own way.
Highway merges, especially in PA (with many short merge zones) could be white knuckle affairs in those underpowered cars.
