That is true especially with a seatbelt on.
A good alternative when in the car is a Magnetic Gun Holster
yep. I use the the magnet down on the panel by my right knee for some trips. Just a little less visible if someone is looking in the window.
I mentioned when I holster while driving, I shift the RH IWB to the left side so its not under the seatbelt. Comes out with a RH cross draw naturally pointing to the driver side door.
