Down here in lower Alabama, at a redlight, people will inch up beside me to talk and I will do the same sometimes. I have always considered that neighborly. There has been times the local 1% MC guys will pull up beside me and ride 2 up on the interstate. I dont like it but I ignore them because they are testing me. I have had them ride peg to peg with me running 70-80 mph. I stay cool and ride 2 up with them for a few miles and they have always pulled off without incident. I dont like strangers behind me though, I would rather be in the back so I can see whats going on and have the advantage if someone makes a move on me.
Just curious, what side of LA are you in? I grew up outside of Enterprise, just a bit north of Dothan
