Well, I see it this way...

90% of the drivers on the road around here want to go at least 10 over the posted speed limit, if not 20.

The cops are somewhat likely to ticket people if they go 20 or more over the posted limit. Basically, they tend to ticket people who are going unusually fast in comparison to most of the other drivers.

It's unsafe to drive at the posted speed if everyone around you wants to go at least 10 or 15 over it. Quite unsafe. It also results in other people getting frustrated because you are driving "so slowly", and then they do stupid reckless things which endanger you and them.

So I normally drive about 10 to 15 over the limit like most of the other cars on the road. This is on the highway. In town is a bit different.

I would be happy to drive the posted limit on highways if it wasn't for the fact that hardly anyone around me seems to be happy doing so.

What they are hurrying for, I don't know. I doubt that they do either. There isn't a lot of self-observation going on out there most of the time....

So I drive 10 to 15 above the limit a good deal of the time when on the highway, but sometimes adhere quite closely to the limit. Either way is fine with me. I adjust my driving to what's going on around me. Whichever way seems safe and sensible, that's what I do.

I don't generally care when I get there. If you leave early enough, there should be plenty of time to get where you're going. If not, well, it doesn't matter much anyway. The world won't stop turning if you're a bit late, will it?
