Really....How do you parallel park.....I think its a great idea....
A lot of the time, if there's traffic behind me, I'll pass up that spot, maybe make a trip around the block.
I'll also opt for walking further, as to not put my car at risk.
I'f I'm lucky, it'll be a spot with a bit of buffer around it and I can pull straight in and even out. I'd rather look like that kind of jackass, rather than trusting someone else is paying attention enough to "grant me" space to properly back into a spot that likely already has two extended cab trucks around it, or a sedan that is pulled all the way forward.
The backup camera in my car really helps things out, but I'd rather not play Russian roulette with a shaky hand and 3 loaded chambers.
It’s all great until you have to pull your car out from behind a crew cab dually and the oncoming traffic isn’t expecting your front bumper. I can see some situations where this would create blind spots pulling out into traffic.
This is a more valid concern than mine, but I guess with this setup, you might have a bit better luck avoiding the cars than backing out of a space (assuming no backup camera)
