Installing car seat is not about showing or avoiding getting into trouble with TP. It's the safety of your child's life. You or your hubby may be a safe driver but not others. I have witnessed first hand the aftermath of the accident scene where my sis & her family were involved in a very serious accident. She herself was pregnant with #2. It's a miracle the baby (my nephew) was fine. And needless to say, my niece was fortunately in a car seat. She was only 1yo+ then. Even the A&E docs at KKH were surprised she came out unscathed. My bil also escaped with minor injuries but the car was almost total lost. They were going straight but the opp vehicle just sped across & their car actually spinned and went to opp side of the road. I cannot emphasize enough how important car seats are. For me, when my babies cry, I just let them be. The screaming and continuous crying can be very frustrating but I'll never compromise their safety. If you really need to pacify them, stop your car somewhere safe and do so. Otherwise, take public transport.
