i remember back in the 80s, when the bbc strapped a camera onto the tank of joey dunlops honda vfr, they asked him how he handled the speed and he explained ‘you say its fast, but it it doesnt seem that fast to me, because im used to it’
or words to that effect, it was a long time ago.
i reckon its partly just a matter of getting used to it.
when i was younger, if on a motorway i would drive at about 80mph, rarely going any faster, just like my dad.
nowadays, conditioned by a 62mph speed limiter on the bus, i rarely touch 70mph in the car, it feels quick to me now.
