I have an idea for another seating option. What about 2 full seats, with a half seat in the middle (2 1/2)? It would fall between 2 full seats, and 3 full seats for the stats (what I was thinking was add on the stats for 1 half seat onto 2 full seats). I don’t know how much this would be used, but it would be neat to have when your making compact and subcompact cars that shouldn’t, or can’t, fit 3 full seats in the back, like Civics and such. Or maybe for those Center Console-Bench Seat combos you see in some Pickup Trucks.
Basically an option for seats like these.
(These are from my 1998 Civic EX Coupe.)
(No clue what this is from, I just Google “Car Hump Seat” for this one.)
(This is from a 2006 F-150 I found on the internet for our pickup truck console/bench combo example.)
