Interesting. I have enough trouble riding on a bike on the highway without thinking about zipping between lanes. We go on country roads where it's more scenic. But I have to drink first to ease my nerves lol
On another forum we had a thread that really got confusing because some were using "bike" to mean a motorcycle and some were using "bike" to refer to a bicycle. I think we need to keep that in mind.
Back to the issue of zipping between lanes of cars where I can somewhat understand it is traffic is stopped and the one on the motorcycle can get between them easily.
