[net.auto] Accelerometer-activated seatbelts

  Many new cars now seem to have seatbelts that lock
up automatically, when the car is stopping suddenly.
This is apparently to allow you to move about normally 
during normal driving without being stopped short by  
your shoulder harness. They are activated by a device  
which senses sudden acceleration of the vehicle.   
  My Toyota truck has this type of harness, and at first 
I wasn't sure what to think because I reasoned it must 
be an electronic gizmo, and how is something like that 
going to stay in action during a collision? But it seems 
to latch up for a few seconds after it's activated, and 
to stay latched if I lean into it. This is like the 
"centrifugal" kind which locked up when you yanked on them.
  An interesting thing is that any direction of sudden accel-
eration will lock mine up: sharp curves, bumps, even slamming 
the door (even with the engine turned off!). It's kind of 
annoying over a bumpy road when I'm trying to play with the
radio, but it's nice on tight turns - the harness holds 
me in. 

  One last thing - I'm getting tired of the "new twist" 
articles. They all seem to all say the same thing and the 
point has been made. What has become increrasingly inter- 
esting, though, is the recent discussion on harnesses for 
short people. I have short friends who wear the harness behind 
their backs because it's terribly uncomfortable and because 
it would probably crush their windpipe in a bad collision. 
How can this be rectified?
