He tweets a plan for a literal LA to NYC high speed rail corridor. And other extreme long distance HSR like El Paso-San Antonio, Portland-Sacramento. He obviously doesn't understand distance, speed, time, topography, and that travelers turn to air if rail is more than 3 to 4 hours. He's a Democrat so of course he doesn't understand cost/benefit analysis.
