Did you upgrade your vehicle insurance? I checked with my insurance company, they would have needed me to upgrade from private use (about $600 annually) to commercial (about $1600 annually), so I've parked the idea for the time being. Also, does it make any difference to the vehicle licensing (rego) category/cost? There's a panel in the relicensing form where you have to specify the vehicle use category, isn't there? The additional insurance cost goes to making Uber driving rather less viable as a little earner for just a few hours a week.
