There's no way my Mustang will be as safe as my Scion xB if I get into an accident, but it's just about as good at stopping as the Scion and better at accelerating out of trouble.
Everything we do is a compromise. Total safety isn't possible- Even agoraphobics have to make some choices, such as cooking meals, or taking showers.
If vehicle safety were the only consideration, we'd be driving Suburbans. Certainly convertibles of all makes would be illegal.
Of course skilled drivers will always have the advantage over an idiot who has no idea how to swerve, or skid, or even look both ways. The trick for the skilled driver is to spot these idiots before they slam into you. I once gave a buddy a hard time because he only looked one way before pulling across a one-way street. He said "It's a one way street, they shouldn't be coming from that side". I said "You'll still be dead".
