The average distance which can be driven once the fuel warning light comes on was collected for 95 models of car from 29 well known manufacturers. To work out the miles remaining on empty, fuel tank capacity and MPG data were sourced for each car. These values were used in the following formula:

MPG x (tank capacity - 10% fuel capacity)

10% capacity is, on average, the level at which the low fuel light shows on most modern car according to Popular Mechanics https://www.popularmechanics.com/cars/how-to/a2633/4252585/

The average per manufacturer was calculated utilising average figures from individual models of car.

1,000 British motorists were surveyed in October 2018 through Maru USURV and asked how far they believe can be driven in a car once the fuel light comes on.
