Guys it is simple.

Going up the ramp:

The car drives up towards the ramp at a steady speed slightly
faster than that of the truck. When the car is close a small dab on
the accelerator pushes the car up the ramp. Then a quick gear
change is needed (probably 2nd - the situation dictates the
gear) before driving into the back of the truck.

Going down the ramp:

The car is backed out down the ramp. When it is fully on the ramp
the clutch is depressed and the car rolls down the ramp onto the
tarmac. You don't need to worry about speed or anything until you
are off the ramp as the truck will now be going faster than you.
Then a gear is selected relative to the speed of travel and away
you go.

The tricky bit is pulling a U-turn when you are out of the truck
to drive off in the opposite direction.

Hope this helps

  If you drove into the back of a truck at 61MPH you would probably go straight
through the front. As for leaving the truck it would probably be OK as long as
the car was only two-wheel drive and one set of wheels did not break when it hit
the road at the end of the ramp.

AT LAST someone that recognises that this 'stunt' is no big deal.

If any of you have seen 'The Italian Job' you would have seen them putting
THREE minis (front wheel drives) into ONE truck! (the last one is a tight
fit)

: Then the background scenery would be going backwards.

Right.  If I had to try it I'd back the car out onto the ramps, put it in
neutral and use the front brakes only (via a line lock) to slowly back off the
ramps.  I'd imagine a manual *** would make this easier too.  Just guessin'

Here's my 2 cents worth:

Backing out is easy - as all seem to agree.

But both going in and going out can be done exactly the same way.  The car
is in neutral without the motor running.  There is an invisible (using
the right colour and some touching up of the film) toe line to the car.
The car is drawn up or lowered down the ramp using the toe line.
There was an old 60's movie called The Italian Job (starring Michael Cain)
in which three minis were loaded into a moving bus in the same manner.

One way to fix your truck so that you can do this is as follows: make
the ramp so that the wheels just slip on it and do not apply motive
force.  If you stop applying power to the car's wheels before going
into the truck, the wheels will just slip on the track, and the car
will slide into the truck because of its inertia.  The rotation of the
wheels becomes irrelevant.

For instance, make a ramp out of small cylinders with axes parallel to
the axis of the car's wheels.  The cylinders rotate freely and so the
wheels just slip without propelling the car forward relative to the
truck.

The only thing that is relevant is the forward momentum of the car
relative to the truck, which is very small and easily got rid of by
friction or by having some kind of padding for the moving car to bump
into inside the truck.

As far as I can imagine this would work for any kind of car (even
four-wheeled drive ones).
