Perhaps a built in device like the steering lock on a car. Stealing a bike
with the front wheel on full lock must be difficult, unless the thievery
is
of the bung it in the back of a van variety. It may also make the bike
more
trouble than it's worth. (to the thieves I mean)

It has been done already. The Raleigh bikes of the 1940s and early 1950s
(the ones with the enclosed chain and roller lever brakes) had just such a
lock, which would lock the front forks at dead ahead, or right or left lock.
But most owners lost the keys.
