I've often wonder this too.
There's already a transponder on the car for timing as it crosses the
timing "loop" at start/finish.
How hard could it be to put similar loops in the places where an
advantage can be gained by going off the track?
I would say this is very hard.
The transponder only has to be on a single position on the car and
trigger the sensors in a consistent way to represent "I am crossing the start/finish line".
With corners - and, worse, chicanes - you car about all four corners of
the car relative to the track, and the kinds of sensors and transponders required to either reliably "beep" when off (or not beep when "not off") would be fiendishly tricky. I'm not saying impossible, but I think the vairious car geometries (despite the formula) combined with the
different shapes and racing lines for the corners make this harder than
we realise.
Perhaps an alternative (though I'm sure there would be arguments) could
be that that cameras and some clever AI algorithms would be more
reliable for this kind of thing.
Any solution would need (in either case) plenty of experimentation to
get right in a fair manner; you don't want (say) the Red Bull triggering
it when it's on the edge of acceptability while Mercedes is able to take advantage...
I don't think this is as big a problem as you imagine.
Imagine a transponder on the centre line of the car at (say) the front
wheels.
If the entire car is off the track in any orientation that corresponds
with the slip angles of a modern racing car, then the centre line of the
car is one half car width further off the track, so place your detection
loop one half a car width from the edge of the track.
There is no way that the system will trigger except when both front
wheels are off the race track. And while it is POSSIBLE that the car
might be understeering so much that a rear tire might still be on the
track, it doesn't matter...
...because there will be a consistent limit.
Let's look at Monza's first chicane as an example.
Place a detection line all the way around the first apex such that even
if the driver goes to the of it, there's no way he can come back on with
out triggering it. All the way out to a point that intersects the right
edge of the track on the exit of the second chicane would do it.
Similarly, the detection line for the second apex wraps around it all
the way from a line that intersects the left hand side of the front
straight until (say) a car's length beyond the actual racing apex. Now
there is no way to cut the second apex in a way that gains you an
advantage.
Finally, add a detection line for corner exit where cars normally track
out; extending it to cover both early and late track outs.
I'll draw it:

Now. Please show me how you could drive through there such that:
1. You don't trigger a detection line if you cut any part of the chicane.
or
2. You do trigger a detection line while remaining on the track.
That it won't be precisely the same limit as previously doesn't present
any problem. All you need is for participants in a sport to have a
consistent rule that they CAN adhere to.
