The police chases are there, but A) there's an intentionally significantly reduced police presence than a GTA (which makes sense from an environmental storytelling sense: Night City having fewer overall cops implies a certain lawlessness to the city; it's also a staple of the genre, with fewer but worse cops a Cyberpunk "tradition"), and B) yeah it did launch buggy, and was one of the earlier things corrected in patches but not early enough for a lot of people that wanted police chases.
