Welcome. I havn't been on here in awhile, but you will find the forum useful and helpful.
I am lucky enough to have a vehile with a backup camara, i really hate turning around too. I drive about 40k miles per yr, so i have become an expert in using my rearview mirror. Just take as much time as you need to get your neck relaxed befor moving forward, it's not important for anyone but you to understand why, they have the priveledge of waiting for you
