I have a 2017 Bolt as my only car and the slow L3 charging is definitely a downside, but I haven't found it to be a huge issue in practice. On a trip long enough to worry about fast-charging you're going to need to stop to eat periodically anyway so if you plan your charging around meals you don't end up waiting too long. Obviously gets a bit more annoying on trips that are long enough to require more than one fast-charge per-day, but I don't take trips that long frequently.

Day to day charging is generally all going to be L2 or even L1 depending on how far you drive and how long typically parked somewhere with a plug. That will be roughly the same speed in any car. Some cars do have higher capacity L2 chargers than the Bolt does, but most public L2 stations don't provide the higher current needed to see the difference.

This I think is the key that most non-EV drivers don't recognize. Especially if you own a home, then an EV is really fantastic. You simply plug it in whenever you are home and 99% of the time you spend 0 time waiting for a charge. The slow trickle charge is both cheaper and more convenient because you aren't making trips to a gas station on a weekly/biweekly basis.

Rather than planning your charging around meals, you're more likely going to have to plan your meals around charging. I don't see a lot of restaurants with level 3 chargers in the parking lot.
