In the episode thread, there is the promo paused on the license. It looks to me that it says it expires August 31, 2020. I did some research in California driver's licenses, and they are good for 5 years, so licenses that expire in 2026 would be issued in 2021. I think 2020 is the right expiration date. I also read that California allowed a delay in renewing licenses because of Covid, but that seems to have expired. So either the crash happened before Kevin's 40th birthday, Kevin didn't renew his driver's license on his 40th birthday and the crash is in the present,or this is another prop goof like the ovulation box.
I have spent way too much time thinking about this!
