You left the scene. What is preventing that lady from claiming that you backed into her? You could be considered suspect and at fault for leaving the scene.
Possibly, but by not notifying authorities, exchanging information, notifying insurance companies, it was assured that she received no consequences at all. Treating her cruelly accomplished nothing.
By not exchanging information, taking photos and reporting to insurance, and maybe filing a police report, you're actually enabling her from maybe running over a kindergartener in the future.
Instead of being mean to the little old lady, you could have treated her with compassion and kindness...
Same with me. I do my own oil changes between the oil changes the dealer does under their maintenance schedules. Oil changes are so easy to do on the 6th gen. I don't even need to jack it up.
Get the Toyota Premium Horn. I got them off of Amazon. They sound great. See several YouTube videos that play before and after sounds. Super easy install.
