Is there anyone using a Tesla Model 3 to tow his/her glider regularly?

Curious about the impact on range and usability to go on (European) gliding holiday.

I found this youtube video of a towing test with a model X. The results were not impressive. They were towing a horse trailer (4,500 lb), not a glider trailer. Power consumption jumped 3.8x at 70 mph, lower at 55 mph (about 2..7x). This was on flat ground at high altitude (less air resistance). My guess is that you will be around 2x with a glider trailer. Better plan your trip carefully.
