Regen does pretty well in my Tesla Model 3. I definitely get energy back. Tesla also did a reworking of regen software (in the motor controllers) in 2019 that boosted the fleet's low-speed regen capabilities all the way down to a stop. So it definitely is capturing energy. Also relevant is this great video about using a pickup truck to charge a Tesla, by towing it. They then compare how much energy the Tesla got from the pickup truck, and how much energy the pickup truck burns towing the Tesla. Watch for the very surprising conclusion! https://www.youtube.com/watch?v=RaGVoB4Zn-Y https://www.youtube.com/watch?v=RaGVoB4Zn-Y
