The bad charging experience is not directly due to poor government legislation. The key is manufacturers need to actually want to sell a car that is able to offer equal end user experience to their fossil fuelled counterparts. Currently no ICE manufacturer is happy to push EV and the lack of investment into rapid charging infrastructure shows this.
Business model for charging operators is simple, blanket cover as much roads as possible with chargers that are used as often as possible. This means single chargers everywhere. But single charger are unreliable as means of continuing one's journey. A single charger can be in-use, causing one to wait up to 30 minutes, and a single charger can be broken, requiring plan B. With multiple chargers at a location, it means virtually zero probability needing to wait full length of charging time, it also means probably of all chargers broken is very low.
But business case for installing multiple charger hubs is not so clear cut. The fewer the charger per location, the higher its utilisation rate, thus the higher return on investment. But to get high utilisation rate, it means end user will likely have to wait -> bad user experience.
Car manufacturers need to invest in charging operators to provide the initial investment for multiple large charging hubs along trunk routes. This, in turn, gives better end user experience and pushes EV as fossil car replacement.
But which ICE manufacturer want to strangle their golden ICE goose?
