Many moons ago we tested my old mans new at the time W126, we managed to go for 12 seconds at 100 mph without touching the steering wheel, speed and smoothness is very deceptive in these big mercs
Points stick with you for 4 years and affect insurance... although his insurance company didnt seem too bothered by 6 points and said it may affect the premium next year but not this year.
A cheap gps/satnav with a speed camera database would probably be a good idea then. At least Dave would be warned about fixed cameras, some also have known mobile camera sites too.
