It is simple to check your own oil, coolant, tranny and wiper fluids, and tire air pressure. Most car maintenance manuals even tell you how often you should. If necessary, it could be included in the test to get a driving license.
Simple for you and I, and maybe simple when people are younger. But would you advocate that an elderly person or a handicapped person who can't squeeze the gas trigger or can no longer see the dip stick for coolants and oil, who can't bend down to remove the tire caps and fill their own gas, would you advocate they can't get a license to drive because of this? In that case, anyone with rheumatoid arthritis wouldn't be able to drive.
I've made it clear already that I do not believe in mandating a no pump law.
