My truck does that. It also tells you if someone is in a seat and not buckled up. BUT, it's easy to turn off.

Big on the OP to not call out the most obvious answer... he knew it.

Viagra.

The only thing that will be "invented" and make more than Viagra is a pill that makes you grow hair on your head like you were 20 years old... but no where else.

One yall home chemists go make that and it will pay off.

Have to watch out for those guys trying to lay claim to your invention.

Windows…the kind on houses, cars, trucks, buildings and such. I see them everywhere.

Home generator business

Good Tex Mex because it hasn’t been invented yet.

Bass boat with an enclosed driver and passenger area with a/c and heater.

Toilet paper

Settle for the toothpick. Was really close on a game camera mount that attached to t-post. Not knowing what i was doing but was over halfway there before i saw the first one come to market.

I have developed, built and sold a lot of specialized welding equipment in this area, it sells itself but I just don’t have the time to present it to everyone that would need it. In the next year or so me and Reelslow will be saturating Texas with it lol.

It was my greatest moment in life. It’s all been downhill since then.

I think it was my 1996 Chevy S/10 Blazer that had an AC/heat vent just below where the steering wheel shaft met the dashboard.
That was pretty nice during the summer.

Not sure on the validity but, I read somewhere that the guy that came up with the K-Cup said he was ashamed of what he created due to all the plastic waste it caused. I am sure he is drying his tears with $100 bills.
