As speed limits on highways have been steadily increasing over time, maybe the "O to 60" metric needs to be revised. Maybe a metric we should be curious about is "O to 75". Since converting 60 miles per hour is 88 feet per second, then 75 miles per hour would be 110 feet per second. Because of the increase in the destination speed, cars will need a longer period of time to achieve that speed compared to hitting 60 mph. Suppose Dr. Lawrence's Impala can go from 0 to 75 mph in 9 seconds.
