How many of you can and do drive?

I have wanted to learn to drive for a while and I’ve just managed to get my benefits redone and can now get a car… but can I really? I was wondering how many people get exhausted just by the mental and physical act of driving? My mother is being a bit of a downer by acting like I’ll be too tired just with the brain power of driving but I am feeling much brighter than I have in years, but I think that’s because I don’t do anything regularly. Thanks in advance for anyone answering.
