Indeed, this is the most important point, the driver being in control, and not surprised by any unexpected lack of grip. Some reduction in cornering speeds combined with predictability being benefits of flat-bottom cars. > > Likely the most valid safety comparison can be made between F1 and > CART; both are single-seater monocoque chassis racing cars, with > *approximately* equivalent speeds and tire characteristics.

Do other people agree with me? Hey, I think you've got something here! Hadn't really thought about it in those terms before, but you are correct--you hear more of people just "losing it" in CART than in F1, where it tends to be "ran into...". > > F1 seems to be relatively safe (no serious injuries in the last > while); this can be largely attributed to the strength of the > monocoque chassis.

Alas, in World Championship There were a few leg injuries in F1 last year; Tambay before Canada (?), Brundle at Dallas ('84 , remember). This year has been quite good, perhaps as a result of FISA's increased crash-worthyness testing. > Rallying, the strength of the roll cage is not as high, and this may > have caused the seriousness of the injuries to Ari Vatanen (driving a > Peugeot in Argentina) and the death of Attilio Bettega (driving a > Lancia in Corsica) this year.

Oh, yes, rally speeds are escalating rapidly as manufacturerers jump into the "Formula 1" rallying. I use "formula 1" in the sense that BIG budgets are going into rallying. Safety may not be keeping up with the speeds. On another note, rallying is a little harder to police with safety crews than an enclosed permanent circuit is. It is also hard to remove trees, etc from a rally course -- the kinds of dangerous obsticals that are not found on other circuits.
