TPS7A6650EVM: TPS7A6650-Q1 Automotive, 150mA, Regulated input

Part Number: TPS7A6650EVM

Good day,

I was reading the device datasheet, TPS7A6xxx-Q1 High-Voltage Ultralow-I(q) Low-Dropout Regulator, but I found this paragraf in page 19:

"9 Power Supply Recommendations Design of the device is for operation from an input voltage supply with a range between 4 V and 28 V. This input supply must be well regulated."

My question is, if the device is designed wit automotive quality Q1, it is not supose to be for noisy enviroments as those give it by a car battery? Or, if I missunderstood what the quoted paragraph before means, could you please explain?
