Real risks (aside from inept fellow drivers driving cars/SUVs w/no brakes or handling) are that: in any collision, esp involving injuries, where extraordinary speeds are involved, the guy driving a new $150K+ car will face scrutiny by prosecutors/civil litigators/media to determine poss criminal charges/civil litigation.....

Even in affluent urban corridors, class warfare implics prob exist in any collision involving high-end cars....becomes even trickier in Podunk/less affluent regions.....

BTW, our German pals will know specifics, but my vague understanding is that, even on legendary, derestricted ABs, if collision occurs and excess speed is deemed to be cause, the errant driver may face various charges (incl criminal if injuries/death involved)....if true, I suspect the Munich/Frankfurt industrialist/financier blitzing on derestricted AB in 599/65 largely faces same criminal charge risks in event of collision w/injury/death as guy in CA, esp in context of any culture that has class/consump jealousies.....

Suspect if one is driving fast enough in traffic on well-known routes to feel "need" for radar detectors, etc, a pre-emptive CHP ticket/warning may actually save one from much more severe poss risks of poor risk/reward judgment....
