Idiotic Ground AI?!?

Ok, first off Merry Christmas and Happy New Year and Yes, I have been drinking, but that's ok as I'm plenty old enough to have Absinthes on Holidays....Now, onwards...Does anybody else have trouble with the ground vehicles crashing into them with little or no warning? Is there any way to edit the AI to be a little smarter? I have just been humiliated several times (4) in front of family and so called friends, including my youngest granddaughter, who has yet to get beyond saying momma and dada, being just 1 yrs old, but can now use the "F" word, in all of its various forms and spellings thanks to me I guess!?! I won't be trying to show the dinner guests my hobby any time soon regardless of the mirth that it brings... Any body got any help or thoughts on the matter?
