I don't know if THE Vanagon ain't got no speed sensor, but MINE does.  Of
course, my Vanagoon also has factory-installed cruise control.

Oh yes, good ol' American ingenuity at its best where a switch, any switch,
will do; where a mechanical device which is designed to change its state
perhaps once a month is toggled hundreds of times a minute, hour upon dreary
hour, and expected to be dependable.  With the availability and dirt cheap
prices of all things silicon, why not merely hack together an active device?
