Elon just bought GM?????

They could improve the mileage of vehicles if they really wanted to. The thing's that they have done that hasn't helped, cylinder deactivation technology, electric steering, multiple speed transmission's. My 2019 Colorado has these features and the mileage is worse than the 2010 Colorado I had. The cylinder deactivation only works going down hill, how stupid, it should work once cruising speeds are reached
