Have not used them but have had 3 negative interactions with them.

The instructors seem to have little to no situational awareness or care for those around them.

Twice I have witnessed them block traffic on a narrow one lane road while instructing students how to parallel park. A one lane road that only allows a single car through is NOT the place to try and teach this skill. Especially when it takes upwards of 5 minutes to successfully park the car. Also there are SEVERAL spacious roads just up the hill that will allow for parallel parking without obstructing traffic.

I have also witnessed them block the driveway of my building for 20 minutes while starting a lesson. The driver parked in such a way that just under half of the driveway was obstructed forcing residents to drive on the grass and in some cases conduct a 3 point turn just to enter and exit the garage. To top it off the instructor was FULLY aware of this and even apologised to one of the residents, but did NOTHING to correct the situation. What makes this worse is that there was plenty of room to move the car forward so it would be legally parked and not obstructing the drive.

After witnessing these incidences I have absolutely no faith in the competency of the instructors and will certainly not be recommending them to anyone.
