For all the people mentioning dashcams, yes get one! Driving in MA is nuckin futs!
I have this one and it's pretty good if you don't have any at all:

But that's a relatively basic model. If you're really serious about it, there are dashcams that record not only in front of your car but also behind and inside. There are kits to let your dashcam continue recording after your car is parked. There is even one that uploads its videos to the internet and sends your phone a notification if your car gets hit while you're away, though it's expensive:
Owlcam - Video security for your car, driving & parked
This channel has decent reviews on cams:

A dashcam is one of the best ROIs you can get in terms of peace of mind.
