Complete beginner - pros and cons of driving, educate me

Zyx:
Thank you all for your perspectives. I really do appreciate it.
As an update, Ive had some serious second thoughts, done a bit more research and had a call from the training service I signed up to (which is Specialised hgv BTW). They put forward that they have a post pass recruitment team that farm you out to companies to place you into the right job. I told them what I would want (see op) , and the person I spoke to indicated that this would be possible.
What do you guys think? Does anyone have experience with this training firm?
