BMTC bus services in Bangalore-a review

While googling Bangalore's public transport system before coming here(that sounds weird but I like to stay prepared and informed before arriving in any city), I noticed that they have two bus passes(Rs 45 valid on non-AC routes, and Rs 90 valid on all AC/non AC buses except the BIAL operated airport buses). The pricing is quite generous given the otherwise high price levels in this city. So having used these bus services extensively in the two weeks I'm here, my observations are below-hopefully they may help somebody else new to the city who wants to save money, carbon emissions(at the cost of time however!)

1. Use Google Transit to find the best bus routes(AC only) between places in Bangalore. The transit times indicated in these are usually quite accurate(god knows how!)
2. Be careful of the bus numbers/routes, as some routes have different numbers/routes while going and returning. For instance, 201R does not pass via Jeevan Bhima Nagar while its counterpart 201RC passes through that same bus stop
3. As the driver/conductor are remunerated partly basis their collections, they try every trick in the book and then some to fill the bus. While that results in the bus sometimes departing late from its starting point, it ensures that the buses do make unscheduled stops to pick up the lone passenger on the desolate road who could really use the bus service then!
4. Hindi is spoken almost universally by the bus conductors/drivers, and many speak English as well. In any case, if you state the place, they will atleast tell you the roads or so. 
5. A slight drawback is the music played in the bus-local Kannada songs-which may turn off those not able to sleep/concentrate on other work in midst of noise. Not applicable for those with headphones.
6. The digital indicator on the bus nameplate also states the route in brief in English AND Kannada. Very helpful to slowly master the routes. 
7. The Volvo AC buses are worth every rupee you spend on them, and quite economical-much more than auto and WAY more comfortable. Only thing, frequency is poor when it gets late, so do call the toll free BMTC helpline to find out details of first and last bus at the odd hours. 
8. Even from the airport, there are the special BIAL buses which take you to many corners of the city. For the individual travellor, that makes tremendous sense than paying 800odd bucks to ferry you to the city centre and so on. 

In short, quite good bus services I must say, both 'bus' and 'service'
