All the things you describe above, the water traps, annoying drips etc, are well known to those of us who wash our own cars and are common to many marks of Golfs.
I'm sure you know this, but as regards drying in general, first and foremost the most important step is investment in a few decent micro fibre towels.
Second is to make sure your final rinse, after shampooing, is done with an open ended hose, working from roof down. This makes the water sheet off the car and is the easiest way to reduce standing water to a minimum. If you just jet wash off, there will be much more water left sitting on the car.
Third is to be gentle and let the towel do the work, gently pat the car dry (no rubbing), essentially what you want to be doing is simply laying the towel on the panel and let it suck up the moisture, as opposed to dragging it along the car, which could inflict scratches and swirls. WoWo drying towels are excellent and absorb huge amounts of water. DoDo Juice towels are also very good. Additionally you might consider using a drying aid or rinse aid, which helps to reduce the amount of standing water on the car - spray the product onto the wet panels and then pat dry as usual - from time to time, I use DoDo Juice Time to Dry but there are others.
But no matter how good your towels and technique, there's no escaping those water traps that continue to drip all over your nice dry car - wing mirrors, door sills, honeycomb grill, rear and front badge, number plate, wheel rim grooves, fuel flap to name but a few
It's really just a case of going round the car a few times blotting the drips over and over, particularly the door sills drips after you've opened the doors and given the inside bits a good dry. Alternatively, some people take their car for a quick blast down the road to blow excess water from it's hiding places. If this is not enough then you could consider investing in an air blower. There are various types ranging from all singing, all dancing expensive models to more modest ones. I've recently bought the one below for this very purpose. I wash my car almost weekly and so for me it's worth the investment.
