It’s not specifically nordvpn. It’s just certain VPN ips in general.

I use proton VPN and about half the time I can’t post without changing where the VPN is connected or just disconnecting.

but I tend to just not bother engaging when it tells me vpns not allowed when I try to post- I’m not jumping through hoops to use social media.

Oversized designs is definitely a big one, but don’t forget subpar training and verification of said training (take a driving test once and your set for life) and of course just overall poor design.

I’ve got a Lincoln mkx and it can be almost impossible to even see out of the windshield on sunny days due to the angle of the windshield catching massive reflections of the dash (like how the hell did that make it past testing)
