I mean… depends on how long you are looking to keep them in. Assuming the community is half way wealthy (which, kind of is normal), then cops and tow trucks would be pretty quick to respond, and well, blocking it with cars etc… would seem prohibitively expensive and legally troublesome (as there’s no way in hell it’s not getting traced to you).

I’d agree with the concept, sabatoging the gate mechanism with a chain, or vandalizing the electronics would likely accomplish a similar goal, without abandoning an expensive vehicle that is easy to trace back to you. (which again, even in the best of scenarios is likely only inconveniencing the residents for a few hours).
