Yes, there is a lot of range and charging-related lack of information. There is misunderstanding of units and quantities involved (kW, kWh, volts and amps). Misunderstanding of EPA tests and the effects of various variables on consumption. Misunderstanding of in-car navigation aids and what you can control manually. Misunderstanding of how to best treat your battery, without going crazy with that.
Some things can be fixed by the hardware (more efficiency, bigger battery, ...), some ca nbe fixed by software (information, better navigation planning), some will require education (ad and informational campaigns etc), some will be fixed by having ubiquitous fast charging that's reliable... etc...
