I went for tethered, its just quicker/easier than taking out the cable supplied with the car, wrestling with it, getting it wet/dirty then wrestling it back into its bag in the rain/snow/cold.
It depends on your drive/charger location, but I only need to unwind one loop from the cable tidy and plug it in, a meter or so away. Takes all of 10 seconds to plug in and walk away or unplug and set off.
The cable is clean, never touches the ground and getting it wet is no hardship – its built for exterior use.
In life, it's not who you know that's important, it's how your wife found out.
