I don't get it. I put my Toyota hybrid in neutral while going through a car wash all the time.
I just googled this. I had no idea this was a thing some people worry about. I guess it's a problem if the hybrid battery runs out while the car is in neutral, but there's a meter right there to tell you how much charge it's got if you're really worried about it.
What surprised me in the video is that Alec was telling how his engine can charge his battery while in the car wash. I had a 2016 Auris which I had to put it in neutral in the car wash, and in neutral the engine couldn't charge the battery. That was never a problem, I never had an empty battery in the car wash or even came close to it, but it does seem different from Alec's experience (unless I misunderstood).
