Maybe your friend grew up in another state that had those restrictions and is carrying forward that in his memory. Another scenario is that some (un)knowledgeable store clerk told him all that and was full of BS!
This last general assembly session the govenor signed into law that everyone (CHP and non-CHP) could carry their loaded gun in a secured container (glove box, center console, brief case, etc). In the past if you did not have a CHP you had to OC it in your vehicle which included in a holster on your hip.
You can point him to this link for some law info: http://www.nraila.org/statelawpdfs/VASL.pdf
