If one were superserious about time from call to ambulanced arrival you could have ambulances scattered separately across the town so that the mean distance from takeoff to accident scene is low no matter where it happens.
Hatzalah and Magen David Adam in Israel actually works this way. They have volunteer first responders throughout the populace, and whenever a call goes out they’ll radio the nearest ones to get to the scene as soon as possible. First responders usually arrive within a matter of minutes—I personally know of at least 3 within a 5 minute walk of me.
Getting an ambulance to the scene for actually transporting the patient takes longer, as these are more centralised.
