ELI5:Why do industrial vehicles use diesel yet cars have a choice of diesel and petrol?

Is there a problem with petrol or is it just that diesel is better. If so how come we have a choice?

Diesel engines tend to produce more torque and less horsepower for their displacement. Which means they can move heavier loads, but do so more slowly.

Diesels are also generally have better fuel economy, longer lives, and lower maintenance costs than equivalently sized gasoline engines, which make them attractive for heavy-duty uses.

Diesel engines tend to be larger and heavier than similarly powerful gasoline engines, which makes them less desirable in small passenger cars.
