I'd like to see stronger (than the Roadster) regen on the Model S AWD model. Regen on the Roadster is limited because it is in the rear (and potentially only one tire). Anyone notice how fast the Roadster rear tires wear out? I think the regen contributes to that more than anyone seems to mention. Having regen on both the front AND rear will really help reduce tire wear and allow for stronger regen (if Tesla allows it).
