I agree with the school that Bear's IQ is more like a Mazda GLC hatchback (I drove one of these - it's a good car, but not a lot of power or speed).
I think Bear needs to be put up on the rack to be worked on. The rack is restrictive and structured with pretty much no freedom, but it allows working on and potentially solving some of Bear's problems. When Bear leaves home he's going get out on the highway and race away, whether his car is working well or not. His drive control doesn't work and he will have a lot of wrecks.
I think Hubby now agrees with me. He'd rather not do it this way, but it's the only way Bear can get the help he needs in the time he has left with the people he has to work with (Grandma and I). If Hubby were home all the time then he could maybe let Bear try things with training wheels and Hubby doing ride alongs, but Hubby is not home. Hopefully Hubby is behind me when we continue to work with the school too.
