We're missing a big opportunity here! Please fill the vacuum

I just learned this year fenders are “wings” in britain. Dont know why.
Sae/metric- my worst experience i think was a timing chain job on an 84 ish crown vic with a 302. There are sae studs into block, that held brackets on with metric nuts.
Think the metric system was put in place during the reign of our present prime minister’s Father. It caused more problems and expenses than benefits.
