They don't have great 360 vision and there are plenty of accidents of rolling over kids playing in the blind spots. They also push the limits of parking space sizes, which both makes them a pain to park and to park next to, and also increases the amount of parking lot space required as larger cars push up parking space sizes.
The only reason we have trucks this big in the US is a shitty EPA law that made it unprofitable to make smaller vehicles for the US market.
