Your three points make absolute sense, but I like to think of the "power to kill" ratio as a sideways curve (see attached image.)
In other words, working backwards, give a kid a 500 hp car, and you can pretty much guarantee he'll get into an accident.
A 400 hp car is not very much safer.
A 300 hp car is a bit safer, but still dangerous in the hands of a teen.
A 200 hp car is a lot safer than a 500 hp, but still could get into trouble.
A 100 hp car is not that dangerous at all really.
A 0 hp car needs to have an IDIOT behind the wheel to get into an accident (and I know plenty of people who could qualify, lol.)
The point being, I don't think there is as much of a difference in safety between a 90 and 130 bhp car as there is between a 130 and 170 bhp or a 170 and 210 hp car. Just look at the graph to see what I mean. I just don't think a 136 bhp car is THAT much more powerful to merit too much concern - that's all.
But yes, all of your points are valid.
Speaking of the qualifying for the 0 HP accident award, some girl at our school managed to roll her Jeep on a perfectly straight and level road at 20 mph... and Jeeps are not THAT prone to rolling over, lol.
