Owning a Z4M surely implies some capability in handling the thing at speed.
Speed isn't reckless...its speed in the wrong context that is dangerous (as said above).
Yes - speed can cause horrific accidents, but in this case, if the road was clear he wasn't putting others at risk.
And ok, he could've lost it, had a blow out and crashed etc, but anything can happen, even when not speeding.
If it was classed as dangerous, then why does Germany have roads that you can travel fast on?
ok, in this country its against the law, and the OP accepts that, but it was unlucky to get caught.
How many people can HONESTLY say they have never gone over the speed limit - if you can say that genuinely, then fair enough, but I doubt many can, and in that car, which is built for speed, then its probably safer than some of the tiny s**t-boxes you see doing 70 on the motorway - or even some of the dangerous types who drive too slowly for the road...i.e. 40 on dual carriageway when everyone else is doing 60+ etc. On some roads, there should be a realistic bottom end speed limit.
