Actually when I think about the traffic conditions for Tapestry or Treasure.
Even thou many people says that Treasure is big development, a lot of cars along Street 11 definitely will be heavy jam moving to PIE.
Let’s say the jam along the new slip road for Treasure to PIE take drivers 20 mins to get into PIE, the proximity to PIE is actually closer than Tapestry or even Tanah Merah.
If you factor in the travel time from Tapestry or Optima for eg, even thou the traffic along Tampines Ave 10 or New Upper Changi Road is smoother and less congested, the amount of time to travel from these condos to PIE might end up be 15 - 20mins including stops at traffic lights etc.
Maybe it might take also same time for someone from Treasure to PIE and someone driving from Tapestry to PIE.
Just my 2 cents
