Road Creep?? real or just a sales pitch for Pier work?

not long ago I heard a foundation "expert" telling a client about how road creep would cause her to need pier work in the future -she didn't need them yet, but she should take proactive steps to avoid the big expense.   it sounded like a lot of hooey but it also sounded reasonable if you bought into his details.  (I suggested she call a structural engineer but she didn't- instead she paid this guy's company to do a bunch of preventive work).

he explained that the motion of cars coming down the street toward her caused "road creep"  (house is facing into a T intersection).  and that vibration will put pressure on the house bla bla bla.  We're in Oklahoma with that wonderful red clay that shifts (and stains your white clothing) and it's important to keep the lawn and foundation watered...but this is the first I've ever heard of something like this. I have observed that the soil changes in different places and houses in some areas are more likely to have needed or had foundation repair, that all makes sense. but this road creep thing....just a little hard to buy.
