I actually hunt my own land where my home, cars, trucks, tractors, and other stuff are within sight. I've had a 10 pt 4-5 yr old stage within 50 yrds from 3 parked cars in my driveway for an hour before crossing the road to a cornfield, almost daily. One of my stands is within 150 yards of my home and my tractor is closer than that by my barn. I guess it just depends on how the deer are accustomed to things like that, because they eat the persimmon off the tree in my backyard. If they are accustomed to this kind of stuff, and it shows them no harm, they become used to it. I see 10-15 deer every time I'm in the stand behind my house, although its wooded and behind a pond, they hear my wifes car leaving driveway and stuff like that and aren't spooked. Its all about where that deer is accustomed to surviving.
