Glitchy Pokémon spawns

Me and my sister love this game it brought me and her closer but there is one problem that almost made me delete the game when me and my sister were on our way home from spring break we took out our phones and a snorlax was at a pokestop and we were in a car and a traffic jam my sister got the snorlax and I did not. I got nothing because her phone supposedly had the speed limit right but mine didnt and I have the worst luck ever so this just made me sad. Please fix this speed limit thing and let us catch Pokémon in the car and collect pokestops in the car. Niantic here me out
