Can't be worse then measuring to the nearest quarter tank. A tenth
of a gallon would be fine for me.  Maybe four sensors; front, back
left, right, and average the readings would probably take care or
most accelerations.  Some anti-sloshing baffles might also help.
Unfortunately, it all depends on what the manufactorers feel they
can make the most profit from.
