C'mon, if it's not overflowing it's not filled up 
15 clicks til full 🙄

Most cars the line from the top of the tank to the charcoal canister has a passive valve, eg one that releases when the pressure rises a little bit, like 1-2 PSI. If you park it with the engine off, even the battery disconnected, it will figure out to do.
But the purge/ vent valves are activated by the computer when the car is running, and abuse could let liquid fuel go straight down those lines to the intake manifold, where hilarity will ensue.

I brim the Touareg; it's a diesel.
I one-click the Honda and round up to the nearest dollar (or $0.01 over).
I brim the Trooper. The charcoal canister is long gone.

ORVR system is not designed to handle liquid. Whether the car is running or not.
The charcoal canister MAY be damaged.

I've been filling cars to the brim for the past forty years.
It's the only way to calculate fuel economy accurately.
That I've had zero problems with the evap system on any one of a variety of cars tells me that this is an old wives tale.
This might happen someday, around the time the sun goes off the main sequences and swallows our planet.

Did that on my VW TDi also. 14.5 gallon tank that could hold 17 gallons. I think the most I ever added was 16.5 gallons.
Loved the cruising range!Anything else, go until it shuts off, done. I pay by credit card, so change doesn't matter, and what am I going to get, 3 extra miles per click?
Yep. Load credit card and loyalty card in. First click. Done. On with life.

If I wait till 0 miles DTE my 13.4 gallon tank will put in 14.5+ gallons at the 1st click. After the 1st click I go to the next 50¢ increment. We live in an approximant world.
Is that the Maverick or the BMW?
Because if it’s the Ford, it’s not that we live in an approximate world, it’s that the car was built for the lowest common denominator -The stupid person that runs it out of gas. Every Ford I’ve owned has a couple gallons left when it shows “empty”.
I will contrast that with Mercedes. If my Mercedes says that 2.5 gallons remains when the fuel gauge shows empty, you can bet your next paycheck that the fill up will be stated tank capacity, less 2.5 gallons when the gauge shows empty.
E.G. The stated tank capacity of my 1981 240 D was 17.2 gallons. The owners manual said that the fuel low light (a little orange triangle in the fuel gauge) would come on with 2.5 gallons remaining.
It happened that one night, on my drive home, the light flickered on as I took the offramp near my house. I pulled into the diesel station, and filled the tank. It took precisely 14.7 gallons when it clicked off.
The overfilling thing is one of my reasons for preferring self-serve gas stations. It seems gas jockeys can't help but try to round up to the next dollar, which is irrelevant in the age of cashless payment.

It is the Maverick. It is a constant topic on MTC forum. One person claimed that drove it for 127 miles after 0 DTE and put in 16.8 gal.
The engine oil capacity of my old Toyota 2.7L I-4 was listed as 6.1 qts if you put in that much oil your dipstick was was WAY over full. A 5-qt jug filled it to right below the full mark. Ford and Toyota must be smoking the same "Peace Pipe". Still a common topic on the Toyota forums.

5th gen ravs have a massive reserve. I think its 2.5 gallons. Once the fuel light are on and distance to empty says 0 you can still go over 200kms.
In the first generation Chevy Cruze community there was a long history of topping off without issue. It turned out all cars had the same sized tank but an Eaton supplied Fuel Limiting Vent Valve located on the bottom of the pump module bung created either a 15.6 gallon or 12.2 gallon tank (6M Eco only). When the FLVV float shuts off the vent to the carbon canister while filling, the escaping vapor goes up the fuel neck and the pump shuts off, and you have to top off to get above the FLVV limited capacity. I found a short FLVV on eBay and the tank held almost 17 gallons with it installed. Driven carefully I made it from Chicago to Atlanta on one tank of fuel, a bladder busting 700 miles. I believe this Eaton style FLVV is pretty common industry architecture around the 20-teens. I think the FLVV makes it almost impossible to overfill the tank to the point of filling the carbon canister with liquid gasoline. I never had any ill effects from the swap, and the evap monitor still set. BTW I do believe toping off can cause the gas station vapor recovery system to have issues.

This! Corolla is 4 point something for oil. I put in 5.0 and it's right at the top mark. Forester is 5.1. I put in 5 and it's about .25 quarts over the top mark by my estimation. Which is fine, cause it'll be down to the full mark within 1000 miles
It absolutely destroys charcoal canisters. I learned the hard way a long time ago and had to replace it. Luckly I knew what to do and got the part pretty cheap. I bet this is a $1000-$1500 job if people take it into the dealer.
I now also use the lowest pressure setting on the gas hose and when it clicks off it's done.

Ours suck gas so fast that they are not overfilled very long at all.
Audi A1 suffer badly from carbon canisters filled with fuel, I’ve changed hundreds along with the N80 valve as these don’t like fuel either. I always remind the service advisor to tell the customer to not over fill the fuel tank.
My LR4 3.0 diesel and Vauxhall Corsa 1.3 CDTI both get filled to the top of the filler neck. As said no issues with doing this with a diesel.

The only time I top off the tank, is when I’m ready to jump on the freeway on a 200+ mile road trip.
