Why do the vast majority of variable speed fans start out on high?

Just about every fan I've used that has 3 speeds - window, ceiling, floor,
etc. - all go from Off to High to Medium to Slow.

The other day I had the chance to use a fan with a infinitely variable
knob
and it too started on high and slowed down as the knob was turned.

As far as I know, only my vehicle fans start slow and get faster as the
control is turned.

It is easier to build the electronics that way or do manufacturers just
assume that we all will use our fans on high most of the time, except in
our cars?

House hold fans come from a time when they were very inefficient and tended
to overheat if started on low. (some would not start at all and if that
happened could cause a fire) BTW heater fans in the older cars had the same
sequence.
