Emergency services need to go from any random point to the nearest hospital" Exactly! And what is the fastest way to the nearest hospital with an open emergency room (let alone a real trauma center) in such areas? I don't know, but I assume that most cities lack real hospitals within fast access of downtown by surface streets (due to traffic, if not also distance). In the San Jose case, you're talking VMC, which would be 20+ minutes away by surface streets but maybe 8 minutes using 280. In San Francisco, the only hospital South of Market is SF General. (Technically South or East of Market, but SOMA is a well-known term).
