They do, they just stopped calling it surge pricing (or anything else). They just show you the higher price with a microscopic grey text underneath that says 'there's a lot of demand, prices are higher now'. If you don't take that route often and know the average price, like when you're travelling or in a city that you're unfamiliar with, you'd be excused to think that's the normal price and just go for it instead of waiting a few more minutes or checking Lyft instead.
