I charge to 80% but find I only plug in my Model Y to charge two times per week. I usually wait until the state of charge (SOC) is down to ~50%. I know that if I need to charge from 80% to 90% that will only take about 1 hour (charging at home at 230V and 32 amps.) Charging from 80% to 100% would take something over 2 hours.
It's a car, there is no way to prevent someone from t-boning your baby or from a crazed forest creature darting out from the side of the road and smashing into your baby. I would not worry about whether to charge to 80% or up to 90%; these things are within your control. Now about that large space rock hurtling through space towards our planet, that I worry about.
