I’ve been shopping around for an emergency jump starter to carry around in the car. I’ve found jump packs that are roughly a little larger than a cell phone, and produce 1000 amps or more. What is keeping them from being a main car battery?

Pb batteries are simpler to keep connected to a running electrical system. If you kept a lithium battery constantly connected to 14.2 volts, there could be problems including cell damage and maybe fires without complex cell management.
Also, lithium jump packs aren’t meant to be used cold. At least, that’s the impression I get from lithium motorcycle batteries. You can keep your jump pack indoors and bring it out when you need it. Pb batteries may lose capacity when cold, but they’re still simply robust.
Speaking of motorcycle batteries, look at how much a lithium battery (like antigravity) costs compared to a traditional Pb battery.
