Great car for an all-round use. Improvement needed

Fantastic build quality and noise insulation. Performance is great on the highway. A variable geometry turbo would have helped in the city. Back seat leg space is not adequate. Feels cramped for 5"8' people. Headspace is good. The driving position is great for a laid-back driver like me. Load it with 4 people with luggage and it will still pull like a beast. Hill climb in 2nd gear is possible if an initial moment is good otherwise need to be in 1st gear. Top speed achieved is 150+. Highway gives a fuel efficiency of around 20 with speeds up to 100-120. City 16.5 to 17 (Depends on driving). The infotainment system is amazing. Complaints. Auto AC does not work that great. Back seat people don't feel the temperature which is set. Blower level set to 4 is also not sufficient. Windshield not getting defogged properly. Rear doors should have opened up a bit wider. And most importantly, the car should not get locked with the key inside.
