I did that in my old RAV4. I coasted in "N" whenever I could, and when I needed to slow down I would shift in to "B" and use as much engine braking as possible first. It was kind of fun.
I've never wanted to do that in my Teslas for some reason though. Maybe it's as simple as not having a shift lever anymore. Or maybe it's just always wanting to have that torque available for any emergency, like a sudden hole in traffic.
I know some people here in WA that have new RAV4-EVs. I wonder how the recall will be handled here. Toyota is refusing to do warranty work, but I am sure they have to do recall work. I just wonder if they will try to get owners to pay to ship the car to authorized mechanics in CA. I don't think they can, they will probably have to fly people up or find people here to do the work. I guess it may be a really simple fix and not matter.
