ELI5: Why do we still have car lighters instead of regular electricity plugs

It seems like no one uses car lighters for there intended purpose anymore but we still use the same plug for charging. Why haven't we switched to plug outlets it seems the most logical thing to do.

Household electricity is AC, your car's electrical system is DC.  It takes addition equipment to convert it to DC, and you lose some efficiency in the process.

Also, a car battery only produces about 500 watts, which is not enough for some high power uses.  Your car's electrical wiring and fuses are not designed to deliver more power than that.  So it is better to have low power DC devices that use one plug, and higher power AC devices that use a different plug.
