I've thought of number one recently as my FIAT went through headlights like candy (I see on the road I wasn't the only one). So I like that. But I didn't know about the AMPS and MPG. Maybe I'll switch to just running. Doing delivery and driving in the Portland metro traffic I absolutely want visibility, and runners would be fine. Thanks for the info!
