Hidden driveway sign is completely useless. No one reads signs and it only does 2 things 1. Gives you false sense of security and 2. Just adds to the overly abundance of signage blight natick has.
I have seen in past complaints Natick does not advocate the usage of speed bumps in the roadway. Not sure if you can legally have them on a main rd let alone any road for that matter.
Best best is to clear back brush, use caution exiting you driveway and possibly ask the police to enhance speed enforcement as capable. Good luck.

It would be good to clear the bush and I would if it was in my property but it is not, doing nothing like you suggest will clearly save town dollars and you some work but we will still be subject to a serious accident, I consider this my notice to the town if something happens we will let the lawyers decide if the town should or should not do something and how liable it will be for the consequences of totally no action

Please contact the Safety Committee through the Police Department regarding this issue
