Thank you to all the Autocar readers who voted in the speed limit survey - nearly 4000 of you. Alongside the charts illustrating the headline results, here are some surprising (and not so surprising) facts that were buried in the data.

  • The average (mean) safe motorway speed was 87mph
  • Among those who always or nearly always break the speed limit, 90mph was considered safe
  • There was very little variation by make of car, although owners of high-performance cars or supercars believed that 99mph was a safe motorway speed
  • Drivers over the age of 45 are less likely to break the speed limit
  • People who regularly speed are less likely to think that the government's eco credentials would be damaged by raising the limit
  • Drivers between the ages of 35 and 55 were most likely to want more police on the road
