Also.. tracks have turns. Low center of gravity helps, but this thing will probably weigh 3-4x as much as a sporty car. Even the Model S has weight comparable to a minivan. My guess is a Subaru BRZ could beat this around many tracks.
This is a cool truck and all, and I hope Tesla makes more exciting designs like this, but I'm tired of people thinking that Teslas are performance cars just because they have torque. Tesla has yet to make anything that interests me at the prices they charge.
