One can have gear and still be neat and tidy and clutter free, its all in how you keep it.
I'd start with one of those small first aid kits designed for a glovebox.
Add in a flashlight with batteries removed and a pack of fresh batteries to go in it.
One of those Window breaker/seat belt cutter tools.
Spare battery for the keyless entry remote.
Gloves, a nice looking pair in the glovebox to use when scraping ice, a pair of work gloves with the jack and lug wrench.
A roll of shipping tape and clear plastic sheet (a pre-packaged clear shower curtain works well) to cover a broken window.
