Some interesting things on this one. First of all Robert, of course you will see lots of old people at older tunnels. WE're in FL, aka God's waiting room. Older people are also the ones with the money. Many of the millennials are still in their parent'd basements. I see some decline in self serve, but nothing drastic. There are lots of people who enjoy using a self serve. The bad ones will die. As to the number of washes per day per million invested, let's have some fun with that.One of the posters said he heard that it would be around 110 cars per day per million. If an average total cost is 4 million, that means they will need to wash 440 per day. And that company at the ICA show that said they would be building one every 2 miles on a 25 mile stretch of highway. That means that every day they need a total of 5,280 cars. Assume most will wash twice a month. That means there needs to be 79,200 cars in that market area. (5,280 times 30 days, divided by two per car per month.) That is a doable number in the north Tampa area. Throw in a rainy month, or several during our rainy season, and I suspect things will get tight. The unlimited wash clubs seem to be doing well, but that is going to eat up a lot of equipment pretty fast. Man, 440 cars per day to break even.
