Well, as one who has driven in New Jersey, you know that hornblowing is another skillset that has to be acquired.
There are rules, you know!!
It took a few months of acclimation, but folks here are patient with you, and more often than not, will stop to allow you to turn left if there is traffice.
People here also wave a lot, whether or not they even know you. It is the neighborly thing to do.
Now you KNOW that is not allowed in NJ!!!!
Sounds like the folks in DE are a bit more genteel in their driving habits. Must be the "rural" environment.
