Building 10 smaller tunnels actually costs more than building 1 regular tunnel; Boring Co's own projects in Hawthorne and Vegas demonstrate that on a per-mile basis they're only saving a few pennies on the dollar, and all of that comes from avoiding the things like fire escapes (the Vegas tunnels don't have any mid-tunnel), tunnels smooth enough for the vehicle/train to go through at fast speeds (the Vegas tunnels are so rough that speeds are limited to less than 35 mph), stations big enough to handle meaningful amounts of passenger (the biggest station can handle fewer than 1000 people an hour), high-strength concrete and surfaces for the massive volumes of traffic, etc. In other words, Boring Co tunnels are cheap because they're bargain-basement quality tunnels with limited use and lifespan. And so Vegas is getting what they paid for: a "public transportation" system that has less throughput than a sidewalk.
