Thing is you may never need to access those plugs. Many have a 100,000
mile life. Covers to stop dirt, damage, etc may be no bad thing.
An electronic 'dipstick' can also give a warning if the oil level is low.
Many people simply ain't capable of using a dipstick and wouldn't know
where to find it anyway. Or add oil themselves.

Electric cars don't have any of that stuff.

Theres at least one in or near the West Midlands that has a dipstick in
it.
