Best of luck. Doing 35mph in a 40mph isn't a problem. Doing 25mph is as it is actually dangerous. It's a speed limit not a target. And how long is too long to get up to speed. Why do you need to rush to get about so much?And why are you going at 85 when the limit is 70 anyway? wonder how many speed tickets you have dodged.
Although I have more of an issue of people going slower than the speed limit, really gets on my nerves people going at 30-35 on a 40 road meaning I keep catching up and having to slow down. Or people who take FOREVER to get up to speed from a stop light.
