Busy busy last night, my first time using the lot. Seems there were an abnormal number of people on the mountain due to a NSride group ride but the lot wasn't quite full although the parking on Coleman had a number of cars in it as well.
There will be an adjustment period; I made sure to obey the 20km/hr posted limit however it didn't help much as there was more than a few riders with dogs off leash running all over the road between the lower gate and parking lot. I can't say everyone was going as slow as I was however which is concerning. Another speed bump right by the crater drop might be a good idea. At the moment it is an accident waiting to happen.
IMO the lot will help to mitigate the parking issues/friction with the neighbourhood, but the setup isn't quite perfect yet. I echo others sentiments as far as the congestion problems and lack of a trail from the lot to above the upper gate.
Just my two cents.
