Getting a speeding ticket while going 3 miles over the speed limit sucks so I can see why you’re upset.
I’ve never had a problem just going with the flow of traffic. Sometimes almost everyone is going over the speed limit. I go with that. I’ve lived in Minnesota most of my life. I’m more comfortable than most driving in snow and ice. Sometimes in snowy conditions the flow of traffic seems slower than necessary. Yet, again, I just go with the traffic flow and end up driving a bit slower than I would otherwise. If there’s little to no traffic I just go the speed limit. If someone wants in my lane I let them in whenever possible.
