Good idea. What exactly did you say / ask them? I might try this with metromile.
I just emailed an inquiry if i am eligible to get discount for driving less. They emailed back with questions on how many miles do I expect to drive in a year, how many days/miles to work and school etc for all 3 of my cars. I responded. Got email back saying they applied the discount. Whole thing wrapped up in under an hour total.
I love GEICO (couple of claims) and never got anything cheaper from anyone else in all these years. I keep checking others from time to time. No one matches their rates for me. I am in Florida.
Hope this helps.
