I chose limited tort. I don't need money for pain and suffering. Under the theory that everyone gets that unpaid with life now and then, anyway. J/K. For me the choice was based on math and statistics.
I've been living in PA for about 10 years now, and I estimate we've saved about $1800.00 in premiums going with limited tort. I've been involved in two accidents (not at fault for either!) since moving to PA, and I would not have made any pain/suffering claim even if I had full tort since I walked away totally fine in both cases. Statistically speaking, if you are involved in an accident, you are more likely to be fine than injured. I can't find more current stats, but in 2015 there were 6.3M car accidents in the US, and 4.5M were property damage only accidents (no injuries or deaths).
