Clever. In fact, so crucial is it that they ought to simply put another
sensor on the other end of the crankshaft :-)

Never quite understood the change from VR sensors to hall effect. VR,
being simply a coil, are far more heat resistant than hall. Electronics
that can get up to engine heat never a good idea IMHO.

But you wouldn't need to put it on the other end of the crank. Simply on a
different part of the toothed wheel and compensate in the ECU.
