gas is probably cheaper here than in europe. the sf to la high-speed rail here is definitely going to cost more than gas prices. it's one tank to make the trip, $50-60, or $100-120 round trip. there's no way the train ticket is going to be that cheap. the new brightline la to las vegas hsr ticket costs $400 round trip. la to sf is a much longer trip and is likely to cost more.
