If you are driving a large vehicle that you are not used to or trained for, you should absolutely not be making high speed passes within narrow gaps in traffic.

Also a 15mph difference in speed should be plenty to make a safe pass.

Finally, going 50mph instead of 65mph for 10 minutes only adds 2 minutes 18 seconds to your trip time.

I’m not sure 15mph is necessarily enough to pass. I rarely pass in those passing zones where it’s one lane each way, but I think I kind of gun it for those few seconds… you want to spend as little time as possible in the opposite lane obviously
