Does the oncoming traffic get strange because of the different position of the headlights?
Actually, I think they pay more attention wondering what it is approaching.
Even my wife comments that, day or night, cars are less likely to pull out in front of the sidecar than they do either of our cars or our other bikes.
My son calls it the "What the h*ll is that thing coming" syndrome.
Could be a semi with some of the lights out. The wider asymetrical light source keeps oncoming traffic at bay.

I once heard a story about a semi driver hauling a load of new cars when his headlights failed. He eased to the sude of the road and found that something must have gone wrong in the wiring. Not to be delayed, he climbed up to the top of the trailer and turned on the headlights of the forward car. This lit the road enough he could safely drive to the next town for help.
On the way he saw a car approaching from ahead. At the last second the car went off the road and stopped. the driver stopped the semi to see if he needed assistance.
The car driver rolled down his window and said,"I'm okay, I got scared at how high the lights were and couldn't see how wide your rig was."

I have ridden my same bike WITH and WITHOUT the sidecar attached.
Never once has somebody tried to drift into me or do other wacky stuff that is a common occurrence when I am on just two wheels. Folks seem to notice me much better, and the asymmetry of the lights does not seem to be an issue.
