So beyond just wearing my car down a little quicker, do you think I’ll damage the car by driving like this?
No one can tell you if you’ll damage the car. We don’t know how hard you’re pushing it, or how often you’re at or in the the engine’s red-line, or if you’re doing any spirited shifting that your transmission doesn’t care for.
I’ve seen many drive like that for years without any problems, and others who quickly discover they’ve brought on some early expensive repairs.
As for all the previous replies and their cautions for driving that fast, many of us drove like that in our younger years. And somehow it takes aging to internalize how little margin there is for error in that kind of driving. You can think of those replies coming from folks who are the ones lucky to be alive to pass on those cautions.
