I had the "truck won't crash through the gate" problem. And I think I found the answer.

Here's the trick: The trigger for the truck to come through the gate involves the player moving toward the gate by passing between the wall on the left and the black car to the right.

Move past the car toward the gate. The truck will start and crash through the gate. If you want, you can jump on the gate as the truck hurtles toward you.

Coming at the gate from any other angle will not work.

Hope this helps.

P.S. It does not seem to matter if you clear the street of opposition or not. All that matters is that you move toward the gate by passing between the wall and the car.
