My 2 cents :
Since Mumbai doesn’t have many Fast Chargers yet, I would recommend the ride length be short and you guys spend more time interacting at a coffee/brunch place.
You could do a quick ride through some of the main thoroughfares (gotta show off right ) and settle down at a cafe for a meet & greet.
That way only people coming from a distance can use the EC to top up and everyone else can leisurely drive back home without waiting in line to charge up (due to a longer route/drive). Once more chargers are installed more folks can join for longer rides since they can top up on the way back home.
Besides, what’s the point of having WARP and driving at 25-30kmph for 50/60km drive
