Seriously just add some motorbikes or bicycles or tractors or whatever can be drivable. Those large maps need it so badly.
And add it in various places not just capture points for fucks sake.
I've had the same experience. No problems finding transports anymore.
This changed indeed with this update. You see the exact transport vehicles location on the deploy screen. They also clean up quicker (if no one is close, they explode) and respawn immediately at their origin for the next one to take it.
I think Al Sundan has at least two vehicles per point.
