I would rather be some place where is doesn't snow !
What a bummer ! I wouldn't be able to change a tire now. My dad showed up to jack up my car and take off the tire and put it back on , I had to take the tire off myself lug nuts and all . We didn't have cell phones then so dad wanted to made sure I knew how to fixed a flat tire if I got one.The lug nuts wouldn't come off so he had to be towed.
Maybe you can fill that gap and come up with the right kind of jack.A lot of cars now are sold without a spare at all. As a large pickup owner I am amazed that with all the hundreds of thousands of larger vehicles on the roads that the portable lifting jacks available are basically not versatile, strong/tall, and portable enough.
In order to be properly prepared you need an air compressor and a heavy high lift hydraulic trolley jack and several sturdy wood blocks. It helps to have more than one kind of jack. This is awkward and a waste of space. It is a different time in history that replaces do it for yourself with expensive service. Still I see a gap in the market for the right portable jack.
