Glad everyone is Ok.
I had a similar incident a while ago. I just calmly kept driving around a neighborhood like I was lost till the guy got tired of following and he took off.
Always stay in the vehicle if you can. You may want to incorporate vehicle training into your practice routine; I.E using your left hand to get your seatbelt off and clearing your shoulder. I do this now without thinking about it. Drawing and clearing the wheel and etc.
