If you really suck at parking in small spaces that much, why not just get a smaller car? plus, isn't bay parking (reverse & front) part of your driving test in other places?
I drive a KA, one thing I love is that I can squeeeeeeze into the smallest spaces that nobody else can but, I can park just as easily driving other cars. I must say I prefer front bay parking to reverse bay parking, though - and all my male friends prefer to reverse xD
I drive people mad when I park because I'm OCD about parking perfectly straight. People in my car are always like "YOU'RE STRAIGHT!!!!" but I'll still have to straighten up to how *I* like it. that's just me being weird, though.
