A car's cupholder is not expected to hold absolutely firmly all sizes and shapes of liquid containers and all quantities of liquids included therein, IMO.

It is easy to claim faulty design for the sake of getting some easy money,  but someone should require common sense from the user in every activity of life and more so in elementary matters as above.

If the case in question is successful for the claimants, car companies might as well abolish cupholders, A car's cabin is neither a cafeteria nor a bar after all.
