Not great for bus at beginning of route – MTA Bus Time Review

Great when you're getting on mid-route. Very precise time and map. However.... drivers turn on GPS when they leave 1st stop. If you're at 2nd stop... there is nothing coming... then arriving in 1 min... Prevents planning to leave with perfect time to catch bus. Frustrating when in the burbs waiting for (late) buses that only come 1x per hour. But otherwise, great technology and worthwhile.
