The 3 point turn wasnt hard anyway so its hardly dumbing down. The test is longer now, 40 mins but mine lasted 50 mins.
Follow roads signs and directions is still there I think 1 in 4 tests are conducted that way. So you have to learn it.
The Tom Tom is basic it doesn't tell you which lane to go its just a route you have to follow.
Good to know about the Tom Tom being basic, but I still maintain that doing a 3 point turn is vastly more useful and marginally harder than learning how to reverse along the kerb (Feek's example).
