Damn, going to jump in the car and get a check. Closest one to me is in Fallbrook. @3 hour drive, ON A GOOD DAY.

I give the guy a lot of credit for trying to create something that can take off. I'm sure the creators of Twitter, Facebook, Snap Chat, Instagrm and the rest of social media had critics telling them it wouldn't work. I know people told me that opening my shop was a bad idea if I focused on smog and not on repair.
Good judgement comes from experience. And experience? Well that comes from poor judgement.
This site redirects to https://www.haloplate.com/smog_check/ which is a generic GPS search site. The first issue with this idea is that not that many searches for smog near me occur. Even if they did this site is not on page one. Unless they actively promote it you are unlikely to get business from it because a potential customer is unlikely to find smogchecknearme.com in the first place.
