Rain X works well on my Westie.  Works better on my bro's Corvette.  Even
better on the local Maseratis.  Even works well on my goggles.  Works
extremely well on the Armstrong Siddley, and the Abarth.  (Local Masers live
at John's Automotive).  Is of limited usefulness in keeping water off the
cat.

However for you syncro offroad type of folks a steering knob allows a new
dimension of backing and filling on those tight corners up Silver Canyon.
Don't go out without "The Knob".  And polish it often, lest it rust.

Those who closely watch after our safety, closely monitored by barristers
and other truck followers have deemed here in Kalifornia that such driving
aids are dangerous.

These folks also would like the building trades to adopt the 'Liverwurst'
hammer.  It doesn't drive nails very well but you can't mash yer thumb.
This proposal is also backed by the local religious groupies on the basis
that society would be much bettered if the seamy language uttered by many
after striking one's thumb with a non-liverwurst hammer was minimized.

Seatbelts for saddles are next.

Be afraid, be very afraid.

To improve the genetic development of modern society, some feel that one
should eliminate warning labels.
