As a SF resident, I can say that it’s really luck. I live just south of the park. It’s not like you’re guaranteed to have your window smashed in, even if there’s something visible. I’ve (stupidly) left tools in my SUV overnight and gotten lucky. Our SUV lives on the street every night, and it hasn’t been broken into in the three years we’ve owned it. A previous car was broken into once over 5 years. And we live on a busy street that sees a lot of shady characters. Our Model 3 lives in the garage, but there are plenty in the area that live on the street.
So yes, it could happen, but you’ll help yourself out by not leaving anything visible and even folding down the seats if possible. There are plenty of street-parked Teslas in both my neighborhood and the one you’ll be in and they don’t have their windows smashed every morning.
