Would it be weird for me to have my 1 hour lunch break in my car?

I’m starting my first full time corporate job soon and for two days we’ll have to come in then work from home till September. I get an hour break and honestly, I feel like that’s such a waste of time. At home, I’ll be able to work on stuff but when at office, it’s such a waste. How weird would it be for me to sit in my car and create designs on my iPad, read, color, or watch Netflix? I have a small business for art on the side and would love to work on stuff for my store during my lunch break. I just think doing so inside the building where everyone can see will look weird vs me doing it in my car
