The extendable lug wrench is in place of a cheater bar. I’m not sure that my relative would permit the emplacement of more tools in the vehicle.

I’ve procured an inexpensive “impact driver to lug wrench” set and a “drill to scissor jack adapter” bit that will live with my battery-operated power tools henceforward.

It wasn’t all that long ago that I learned that an impact driver (typically battery operated, designed for driving lots of fasteners quickly) is not the same as an impact wrench (typically operates on compressed air, designed for high torque applications). Impact drivers carry somewhat more risk of injury when used on lug nuts.

Up until now I haven’t wanted to invest in a nicer jack to carry around, or chocks, due to space constraints. If I ever go back to driving a larger vehicle I may feel differently, but the trunk of my car already has a lot in it. It would be easy enough to have those tools at home for issues like this though. I’ll look into it.
