Unsafe Smart Cruise Control

the 2021 Santa Fe smart cruise control cannot be disabled so that you can use regular cruise control. Let me share why this is a safety issue and ask other owners if you would chime in so something can be done about it.

I am in the left lane with cruise set at 75mph and 1 car distance. The distance between me and the car in front of me is very generous and invites other cars to get in front of me. My speed suddenly goes from 75mph to 54 mph. Before the car can automatically accelerate, other cars are getting in front of me, thinking i am a jerk driving in the wrong lane when in fact my speed is set over the speed limit. Not only does this impact cars pulling in front of me, but the sudden drop in speed causes near rear end collisions as there is no warning to the drivers behind me that my vehicle is slowing over 20mph instantly.
So far, i can only use this dangerous smart cruise when there are no other cars near me on the highway which is not very often.
Odd that a feature that was intended to promote safety has taken the control away from the driver who is ultimately in charge of that.

We have taken this issue to 2 dealerships, we have 2 case numbers with Hyundai Customer Service who fails to contact us back.
Next step I guess is to go to arbitration under the Lemon Law if Hyundai refuses to acknowledge and fix this problem.
I have a more serious issue. In my 2021 Santa Fe, Limited, when I turn on Smart Cruise control, I get "Emminent Collusion" warnings in the dash board, "Front Radar turned off, "Front Collusion Disabled, "Side Safety Features disabled. So it disables all my safety features. I am trying to get an appointment to where I recently moved. Service dealers do not think it is serious issue. ????. But with smart off , there is not standard cruise control to fall back on.
