[On tilt-meters in off-road vehicles] Message-ID: <627@mtuxn.UUCP> Date: Thu, 22-Aug-85 15:51:35 EDT Article-I.D.: mtuxn.627 Posted: Thu Aug 22 15:51:35 1985 Date-Received: Sat, 24-Aug-85 16:25:37 EDT References: <10041@ucbvax.ARPA> Organization: AT&T Information Systems, Holmdel NJ Lines: 13 If you are taking a corner at 25 degrees "tilt", you are probably going rather fast on a paved road. Large bumps are not to be expected, and if you see any ahead you can slow down. You will probably also skid before you roll (see below). On the other hand, bumps are fairly common on hillsides and slowing down doesn't help much. Psychologically, when taking a corner you can still *see* that you're on flat ground regardless of what your inner ear (or tiltmeter) says. The brain probably averages these readings somehow. Jeeps *are* infamous for capsizing in turns on the highway, because of the above illusion and because (unlike cars) they will roll before they will slip sideways appreciably. Wider modern 4WD's aren't as bad.
