Over 7 years ago, Elon Tesla said that doing autonomous vehicles using high-definitions maps was impractical and too expensive. Looks like some companies are finally giving up using high-definitions maps.

Huawei scraps expensive precision maps in self-driving cars
Huawei and other Chinese self-driving car companies are developing alternative technologies to high-definitions maps as the precision required for autonomous vehicles makes the mapping process prohibitively expensive.

"High-definition maps are very expensive," said Huawei senior executive Yu Chengdong at Auto Shanghai show on April 16. "We have been collecting data in Shanghai for one or two years, but we still have not been able to cover all 9,000 kilometers of the city's roads."
HD maps for autonomous driving require technology more advanced than those for standard navigation systems. Maps accurate to about 10 meters are sufficient for navigation systems, but accuracy to about 20 centimeters, and in some cases as low as 1 cm, is necessary for self-driving cars, according to a Beijing research company.
The survey cost for a map with 10-cm accuracy is 10 yuan ($1.44) per kilometer, but for accuracy to 1 cm costs up to 1,000 yuan ($144) per kilometer, according to a 2021 white paper by industry group China Industry Innovation Alliance for Intelligent and Connected Vehicles.
