Hey there, got an unusual question:

I live out in the country and part of my front yard is on a curve.
Constantly when it is wet outside, cars go too fast around it despite
signs being posted and end up sliding in my front yard. There is a
small ditch along the road that they go through and into my front
yard. Yesterday, someone even took out a bush I had planted at the end
of my driveway.

ANy bright ideas on what I could do? I thought about taking a tiller
and making the ditch deeper where it would be harder for cars to go
through. I even though of welding together some sort of guardrail to
but on my side of the ditch.

Any help woould be greatly appreciated!
