I haven't watched the crash and don't intend to, but I don't see how any sort of electronics is going to help when a fallen rider is hit by a bike (or two). Rotax mentioned Craig Jones, similar sitch: rider fell, got hit by another bike; unless the electronics you're referring to are forcefields there's not a blind bit of difference they're going to make.

- riders fall off without electronic aids*
- there is a chance a fallen rider will hit an object
- there is a chance another vehicle will hit the rider
Teams and riders will always adjust to compete with what's available to them (technology, rules limitations etc.) in order to win. I remember a couple of riders explaining why they were unhappy with the 800s compared to 990s: corner speeds were/are higher on the 800s so it felt more on the edge and dangerous, even though capacity was reduced to supposedly reduce speed (which it did in a straight line) and make things safer (which it didn't as mentioned before). Did any of those riders slow down because they felt unsafe? Did they bollocks, they want to win.
It doesn't matter what rules or technology are in place, racers will always be on the limit whether in MotoGP or MopedGP. Rider safety is a by-product of competitiveness anyway: a rider who falls off and breaks his bike doesn't win. If a team wants to win they want the rider to stay on the bike.
Sure, vehicle safety is more obvious in car racing with roll cages and survival cells or whatever. I think circuit safety is a bigger factor in bike racing - is there enough run off in place, no obstacles to hit etc. We see riders walk away from some horrific-looking accidents, and while highsides are likely to cause nasty injuries they're not likely to cause death. The danger is when another object comes into play.
Whether you admit it or not,that is half the fascination with it - the risk.
It's a lot of the reason I watch all types of bike racing but find myself falling asleep when the vehicles racing happen to have four wheels.
I dunno, there's been some bad events recently: Dan Wheldon killed last week, Felipe Massa brush with death the other year, an impressive (noni-injurious) crash by one of the Audi's in this year's 24 Heures du Mans:
The photographer running away is slightly comical
*I'm not referring to the electronics aiding the falling off, whatever it sounds like.
