That's quite an easy one..
Many test centres are too far away from a motorway to make it viable to use in a test.
The test is only 40 minutes so, in order to get everything else in that they need to do, you can't be more than 10-15 minutes from one AND be able to get off it and back to the test centre inside that 40 minutes.
We're 30 minutes from motorways in every direction.
Post-test training is available but few want to spend the money.
I'll rephrase, you can't drive on a motorway until you've passed a separate motorway specific test. If you live in the sticks, no need to take one, seeemples.
