One suggestion I would offer to Tesla is they need to address road noise. For the cost of an X I would expect it to be at least as quiet as a BMW or Mercedes SUV especially since there is no engine noise. But my X is as loud as my wifes Honda Pilot. The solution is simple.. just add more & thicker sound absorbing insulation around the cabin and on the floor. The cost to do that seems negligible. They should use the Lexus LX as the mark to shoot for in cabin noise.
