I need help with this trophy

Came across an AFK glitch to do this trophy I’ve been doing it for over 15 hours and I’m on 5 million points. I started with 600+ miles. How long would I have to wait for it to get to 1000 miles? Btw this is my 3rd attempt to do this trophy & i cant check as it errors out when doing the glitch.
