IMHO, I feel it’s mainly 3 reasons:

1. With many people from NY moving into NJ because of COVID, who have never had a reason to drive and suddenly they’re driving on major highways, there are many more erratic and inexperienced drivers causing traffic and accidents on the road.
2. NJ inspection stations have not failed vehicles for mechanical faults in years, instead simply checking for a CEL. This results in unsafe cars that may look fine on the outside but have no brakes, bald tires, lights out, blown shocks, etc. These all relate to longer stopping distances and major instability at speed.
3. Lastly, the general performance and sportiness of cars nowadays is truly amazing, but scary for many people on the roads. Look at the last generation Accord 2.0sport. It’s a family sedan with a quarter mile time equal to a dedicated sports car of only 10-15 years ago. Mix these all together and I feel this explains why NJ roads are the way they are.

LOL no way southern Warren county is considered Central Jersey. Nice try.
