If you adjust your lights when there is no load in the vehicle, then put for adults, with luggage in, you'll find your lights pointing up into the air, blinding oncoming traffic.
Ok, adjust your lights for this. All is fine.
Now, when everyone hops out, with only the driver in the vehicle, your lights are now pointing several meters in front of the vehicle, totally useless!
Hyundai, you provide this function on the i30 elsewhere in the world, why not Australia? If it costs an extra $150 to implement, then I would gladly pay for this functionality at time of purchase.
ADR's have nothing to do with it since there are many EU spec vehicles here with headlight levelers on them.
Hyundai, please consider!
