Construction Simulator

With this i think you just cant bump into an ai car or possibly bump into the world. Rather easy if you turn off traffic and drive carefully. I would just use the civilian pickup because its fast and nible. Personally i picked up this after fast traveling to a construction site and doing 2 minutes of dirt moving with a track dozer. That thankfully means that you dont have to do 1 solid hour of perfect driving but rather just trying not to get into any accidents while you drive. Sad thing is neither the game or the achievement give you any feedback on how long you have been driving accident free so its one of those wait and see achievements. Nice thing is all i was doing was moving dirt at a reasonable pace with the dozer so the required speed is low. Probably did help that i spent 40 minutes driving around the map trying to make it pop before quitting.

Hard to say what constitutes an "accident", but I think it might only be hitting AI vehicles. It took a while for this to pop for me, so it may only be cumulative in chunks. Either way, turning off AI traffic in the settings sure makes it easier.

Unlike All In View (5hrs in first person), this achievement will not pop if your vehicle sits stationary while you're AFK, even on the road. You may need to be travelling above a certain speed to be considered "driving". Unfortunately it's a 0->100% achievement so impossible to tell when you're accruing time and when you aren't.
