could be the cop(s) ran the plate and knew who it was - maybe it was a kid or their parent(s) are a somebody - and decided to let them go, otherwise yah it's not terribly safe to have a high speed chase through the streets of simsbury where a bunch of families with kids live, I should say privileged and entitled families with overzealous helicopter parents who complain about anything and everything like if you fart too loudly in town after 9pm
