I find my X nearly impossible to drive on the highway, unless the roads are smooth as silk and there are no other cars driving at all.. its unbearable. Any truck, any loud engine car that drives by is so damn loud it sounds like its going to run into me. It ricochets in the cabin. The ride is so rough, I cannot take it anymore. I asked Tesla to buy my car back, I think Im in for a big loss. Oh well. Only 1800 miles.. so much for that. Here I thought those Consumer Reports guys were on crack.. but they were right.
