I don't know. If I was looking to top up my Tesla's battery and I saw an ebike in the charging bay I might just crush it with the front wheels and/or give the owner a spanking. There are must be dozens, if not hundreds of public and semi-public 120V outlets in walking distance of nearly every urban and suburban location why would it ever be necessary to use vehicle charging stations? Plus you will need to drag your charger around. Practical? Ride within the two way range of your battery. That distance is further than you think. Unless you are using a fast charger, you will not benefit much from a public charger. And if you are using a fast charger, you are taking days off the life of your battery with every use. $85 - $99? Plus the above ... I wouldn't do it.
