Driving with ocd -advice please

I’ve avoided driving majority of my teen years because I got into a head on collision when I was 17. Even before then, I was absolutely terrified of driving. Saying I was terrified is an understatement. I’d literally shake at the thought of anything to do with cars and imagine my body scrunching up with the car metal after getting into an accident. OCD would convince me that I simply cannot trust myself behind the wheel, and that something bad will happen - like I’ll kill my self, someone else, or an animal and I hated it. Needless to say, I genuinley could not bring myself to get started with driving until I was 19, which was a few months ago lol. I got my permit at 17, practiced driving a tiny bit then stopped after the accident I got into. I eventually got the permit renewed a few months ago at 19, then I finally got my license a month after. Now I’m 20, and today I drove myself 45 mins to and from work! I still need to practice more, but holy lord I never thought this day would come. All the years I’d feel embarassed/judge myself have come to an end. Just because I was delayed at doing something doesn’t mean I’m not capable. For anyone who has goals they want to reach and they feel like they’re impossible - they’re not. Fight OCD as best as you can. I hope I can be a symbol of hope for anyone whose struggling

So today I’m getting my car back from my grandparents bc it had no ac and they fixed it for me the day I gave them the car I was having ocd bc I touched a little tree air freshener no the air freshener itself but the outside of the wrapper and then I touched my steering wheel and I didn’t clean it before I gave it to them and I was having really bad ocd that day about it and now it’s coming back because I’m getting my car back today and I have a cat so I’m just always overthinking bc of her with the things that have chemicals on it common sense makes me feel stupid for feeling this when but I genuinely get overheated having to pick up this car today because I don’t wanna deal with it and it’s hair wash day and laundry day and I feel I should clean my steering wheel and ik I’m gonna have to wash my hands a million times and everything I touched after touching the steering wheel like my phone and the car handles and my front door handles. Should I just try and not do these things bc it’s common sense that doing all the this is necessary but I feel I need to I know I’m just needing reassurance I know I need to do nothing but I always stress about my cat and I go to the laundry mat to do my laundry so I don’t wanna be sitting there overthinking about my steering wheel bc I could of just simply wiped it down but I don’t wanna repeat the cycle of giving in to my ocd

I have been in ERP therapy for my OCD for nearly a year now. Before my diagnosis and doing ERP, I really didn't drive a car for five years and rarely left the house. Now I drive to work, coffee and other outings. Most of the people close in my life don’t really know about my OCD. They do see me doing lots of things I haven't done in the past. I don't really know if I should explain about why this progress happened. I hope they don't think I was just being lazy up until then. They will talk about how someone is “so OCD” because they keep their room clean and really enjoy things neat. Anytime I hear this, I just think that if they hear about my diagnosis of OCD and what it entails they will think I’m crazy. I feel very conflicted about how to go about this, so advice is welcome.
