So we've been in our house for a year now. Last year, the neighbors across the street weren't staying in the house due to some sewage backup in the basement and the decision to completely redo the house. They have recently started staying there more and I've noticed a few trenches at the edge of the yard along the curb to the street. One considerably deeper than the others completely removing a good chunk of grass. No guarantee it is them, but it looks like it. My camera is set up to record when people are closer than the curb, otherwise my phone would chime constantly. They seem pretty nice and I'm not going to start blaming people for E36 M3 that I'm not sure about. In addition, I'm not going to blame them for their visitor's E36 M3ty driving.
My lawn is no work of art, but doesn't look bad and I'd like to get it looking better. The lower portion of the yard will be very soft in the spring due to the way the drainage is set up.
What are some things I can do to keep the neighborhood cars out of my lawn? I thought about some reflectors or small boulders, but I thought the GRM mind could throw some other options my way. I have no HOA and city code is pretty loose.
Also, my wife said no "active land mine" signs...

I understand this sentiment.
In reply to Grizz :
I suddenly feel better about my situation.
Shrubbery. Boulders. Hedgehog anti-tank barrier. Listed in order of increasing effectiveness.
As I have 10 acres of rocks, I'd go the rocks route myself. Then those anti-tank things. Can't be that difficult to weld up.
Tiger pits. Or rocks. Whichever is cheaper or less illegal.
Or burried Takata airbags.

The upside to the guy in the dually not even trying to brake for the corner is that I got a free aluminum ladder out of it thanks to the black walnut snatching it off his truck
automotive punji sticks. just a thought. 
GRM, you never fail to make the best suggestions.
Big rocks.
Or an unemployed sniper, but that might be extreme

Yeah, I agree, rocks are pretty extreme, but sometimes you gotta do what you gotta do.
Throw a handful of roofing nails along the edge of your grass and see who in the neighborhood suddenly has two flats on the right side of their car.
Seriously though, it's probably the mail delivery person. Ours just drives down the road with two wheels in the dirt the whole way. Since it seems like a newish issue for you, maybe it's a new person driving your route?
You already have a deep-ish trench, just take it up a notch & make a full moat. Bonus points: you get free future Challenge vehicles.
Find an old police spike strip on one of the government auction sites & lay it perpendicular to the road?
Rebar is cheap, pound a bunch of it into the ground on the perimeter and sharpen the exposed bits. Severe tire damage.
Whatever you put out there is going to bite you or your buddies in the behind some day ,
55 gallon drums of dirt with reflector tape on them , or arrow signs pointing back to the road.
Or make a cartoon drawing of a truck sinking in quicksand !
Before I did anything too extreme, I would find out whether you actually own that property. I bet the municipality does, and anything you do would be reasonably illegal. A four foot cut with crushed rock might be accepted, but I'd be real careful about installing claymores.
Instructions seem pretty simple.
Get a garage door opener and either a foam deer target or one of those light up Xmas deer, and point it at the road.
Them Flamingo lawn ornaments with their names on them or cute names like Pookie. When one gets crushed take it over and ask if they know who killed your thoroughbred $5000 flamingo and who is paying for the funeral?
I'll have to put some fill in and plant grass in the spring. As soon as I do that, I honestly think I'll put flamingos out there Cheap, easy, and hilarious.
