Question or two about orthodox community nearby

Hello, I live right next next to Lakewood NJ and there is a massive orthodox community, and I’m curious about a few things.

I’ve been seeing a lot of jews lately driving teslas on Saturday during the day, is this allowed now? My brother in law is jewish but hes not orthodox, he says its forbidden but I’m curious if something changed.

For all my life lakewood has had this massive orthodox community, what caused it to form here anyway?

And why do all the reform Jews in the 55+ communities near me hate the orthodox Jews so much? Everytime the orthodox Jews from Lakewood try to purchase a property in my town or build a school the senior citizen reform Jews protest it and complain to the township and cause problems

Edit: fixed some typos and clarified its during the daytime i see the driving
