Not everyone who owns an M-B has had the experience you have...
eg: spannering for the great racers...... going on errands for The Beatles, etc....
Meaning a lot of experience and common sense.

So a bit of 'prodding' (from M-B) in telling the average guy (or girl) where the speed limit in town is, would not be too bad.
Forgive them... be gentle...
I am not sure The Beatles ever made a contribution to safer driving, but I get your point.
BTW, I tried a bit of racing Formula Fords in the eighties, I was no good, not only falling off and making mistakes on the limit, but my limit was not even close to competitive speeds so I packed it in - not good enough.
BUT, the tuition I had, and the experience on the track immediately made me a better safer driver on the road, and I think anyone who thinks they like to drive fast would benefit from some good track time.
I also knew a cop who was trained in high speed pursuits, and he showed me how they are trained to 'read' the road and traffic conditions to anticipate all potential hazards.
If the hoons who think it clever to race around in public, spent less on hot goodies for their road car and instead took up racing at club level, they would probably learn a few good lessons too.
Even Karts, sprints, hillclimbs etc, or a few days at a racing school if you can't afford real racing, would get it out of your system, and I for one was happier to be slower, but safer on the road.
Which gives me an idea!!!
How about a track day for the Benz brigade?
I guess we would all be left behind a well driven 6.9 or similar, but any car driven to it's relative limit would be an education.
