On my way home from work there is one particular intersection where my FFH keeps giving me hugs. By hugs I mean the seat belt not only locks up, but actually tightens a bit. This particular intersection is where a country road meets a to lane highway. The highway is on an incline and just past a pretty severe curve. The vast majority of the times that I take that corner I have to accelerate a lot harder than normal as when I pull out a car comes around the corner and I have to get up to 55+ mph a lot faster than normal. In the first month that I had the car the intersection also had quite a lot of ice built up and I'd spin the tires a little. Between the hard acceleration up a hill and the slippery road I just assumed the car was getting ready for a crash as I've had this and other cars lock the seat belt in similar situations.
For the past few trips home though the roads have been dry and there has been no ice. In addition I've accelerated at a more normal rate as I didn't have another car barreling down on me. But the seat belt is still tightening up and locking. And where I've had other cars lock the seat belt in similar situations I don't recall ever having them actually tighten up around me.
So... am I just fretting over nothing? Is this normal behavior? Does taking a 90 degree turn and immediately accelerating up a hill equate somehow to my car getting nervous? Or is this something that I should worry about?
