I can feel how my car drives with and without my side mirrors on since I put them back on any time I go somewhere for an oil change or tire rotation and balance and so on. I know it’s not scientific, but it’s like muscle memory.
For example, people here are telling me to start my “ boat tail” at the end of my spoiler, and not to follow the roof line of my hatch because it doesn’t “ match the template “
But I’m assuming I can just extend the roofline and then add a spoiler for pressure recovery and maintain attached flow and tuft test it. Obviously I’d be able to “ feel” a diff with a boat tail keeping attached flow even if it’s not the template. I mean a Tesla model 3 has a pretty steep rear roof but a little spoiler and keeps attached flow
