From my experience driving my ex-914 to work (rarely) and my Mr.2.
People don't see you.
OR
They do see you and decide you're the one they are going to cut in front of to get into the lane you are in.....and then, of course, hit the brakes.
There is an art to driving a small car in traffic..... a larger car /truck also, but the small car makes it more perilous. You have 2 choices:
1) Let them run into you.....but don't rear end em'.
2) Yield. You can add the single finger salute (which is now against the law in many states) but be prepared to back it up. I reserve that for the cut-in-brakers.
I'm getting old and am gonna get my ass kicked one of these days.....but it wouldn't be the first time.
So, yes, 914s & 914 drivers are susceptible to front end damage.
I had a Lotus Elan S4 in England and was always having to repair the front end (fiberglass) due to drivers cutting in and braking or just braking in stupid places, where you would least expect it.
