I've had my beautiful Prius v for almost a month now and have almost been hit twice by the jacka.s in front of me while waiting for the light to turn green. The first time I had plenty of room (several feet) and this car in front starts rolling back (seemed like a stick) but instead of the normal several inches rolling back it was the 3 feet of room I had left. While he was rolling back I was laying on the horn but to no avail...he just kept coming. I was looking behind me to see if I could back up to get out of this guys way but I had cars behind me. Luckily he finally stopped (had to be just inches from my bumper). I was very close to having a heart attack with my 2 week old car. The second was this morning, again waiting at a light, the SUV in front decided he went a little to far across the crosswalk (not actually blocking the intersection) and then pedestrians started to cross, so he puts it in reverse and starts backing up towards me. Again after the first foot of him backing up I lay on the horn and again he keeps coming. I finally put it in reverse and backed up (luckly no cars behind me thank God), while still laying on the horn. He finally acknowledge me with a sorry wave .... But still !!! Just stay put the people will walk around you ! Sorry for my rant, I thought the horn on the Prius v sounded pretty decent (better than the meep meep type horns) while I was outside the car but obviously no one can hear it (or is it just mine they can't hear?). In my old Escape I never had this problem, let alone twice in one month! I just placed an order for a set of Piaa 400/500hz horns tonight, I just hope it's louder and people will stop backing up towards me...maybe I should just leave one or two car lengths between me and the car in front of me while waiting at lights from now on. Or maybe look for a train horn, that should be loud enough. I've read several forums hear about the Piaa horns vs. the standard Prius horn but not much mentioned vs. the Prius v's horn. If anyone has knowledge of a comparison to the v's horn I would love to hear if it's worth it to switch the horns or look for something stronger (possible some type of air horn). Thanks. Ok, ok really end of rant now.
