I was going to add that option a couple of weeks ago, but I did something else so easy that made the problem go away so it's not necessary.
I increased the speed of the car to 16mph. That's all it took. I'm usually in an A320 or B73X, so I rarely make turns at more than 10 mph and rarely exceed 15mph on all but the longest of straightaways. With the car at 16mph, when I start rolling, he gets far enough away so that when I get to 16mph there's plenty of room between us. He slows down in the turns, but I need to as well, so he's usually speeding up again when I get to 10mph in the turn.
Maybe Umberto could make him slow down a little less in the turns? That would be nice since he gets a little sleepy going around them. I'm often behind him wondering what fool gave my granny a job driving a follow me car.
Try it. You might find a speed that works for you.
