It's over 200 out of about 2000 at Harvard, plus another 200 for athletes... Though of course the bigger issue is that Harvard only has 2000 places for undergrad despite a $50bn endowment, in order to create some artificial scarcity.

You forget that most people don't live or work next to the rail station. That makes rail inefficient in the only way that matters to most people - their time. (I say that as someone who takes trains to work most days.)

Untrue. Power plants can be 50-60% efficient (and up to 90% if the waste heat is used for district heating). Meanwhile car ICEs are at best 25-30% efficient (slightly more for diesels). Even with transmission losses of 4-6% and electric car
