Guess that depends on your location - in the 3 European countries I've lived in, Deliveroo and Uber drivers/riders almost universally had insulated cuboid bags (usually with one of the companies' branding on) in their car or on their bike in all three countries, while Dominos pizza was the same in one country, in another country Dominos used cars with no insulation except the cardboard pizza box, and I don't know about Dominos in the 3rd.

(And I'm not sure if my experiences were representative of each country, just that they were consistent in each city.)

Uber Eats drivers definitely don't have them where I live. Food almost always arrives cold, even when the delivery time is very short. When I lived in NYC most deliveries were done by bike and all of them had insulated bags so the food was typically warm unless it had been super delayed.
