There used to be takeoff minimums where a turn was required as soon as

It doesn't really apply to GA aircraft anymore, but the departure from
DCA's runway 1 requires a 40° left turn fairly soon after departure to
avoid overflying P-56 (unless, of course, you can make a climb rate of
something like 12000 fpnm)
