It is intrinsic to autonomous driving. But MG don't have autonomous driving, just driver assistance systems.
Newer cars (including mine) removed the sensor, probably because of all the reports of false positives. It might reappear, but for NCAP reasons rather than AD.
I've tried TJA on the MG4, and I definitely wouldn't be taking my hands off the wheel
On a side note on features like BlueCruise: I don't like them one bit.
These are L2 ADAS features that are being miss sold, where customers are often under the impression that they are 'self driving' features (Tesla FSD).
For all of these (despite hands-off implementation) the driver is 100% in charge of the vehicle and 100% liable for the vehicles actions.
These features are a dangerous half-way house between autonomous driving (L3) and ADAS (L2). The even go as far as to call them L2+ features, further muddying the water.
