So I just got back from Vietnam. Had a great trip eating (and following Luke Nguyen's recommendations in Street Food Asia) 
I relied on Uber mainly to get around. The reason being it was convenient - all I had to do was punch in the addresses in the app and voila the car arrives and drops me to exactly where I wanted to go. No need to pull out a single $$$ (dong), and didn't even need to speak a word of Vietnamese! And everything was GPS tracked so nobody was going to take you on the "scenic" route (not really relevant for Uber), but i took a cab once and just tracked its route using google maps to make sure everything was on track (having said that Vinasun and Mai Linh cabs are known to be generally safe and reliable and you should only take those in HCMC).
But that got me thinking, back in the day, if you wanted to go around, you will need to talk to the taxi driver (or motorcycle taxi) to get you to your right destination, sometimes try to negotiate a fare, and generally try not to be scammed.
Or if you wanted to visit somewhere, you would need to pull out an old fashioned map and try to navigate there (no GPS and google maps!).
And with money, you generally brought your money with you and tried to ration/protect it and you perhaps needed to find a money changer (now, you go to the Citibank ATM
- I am actually thankful for this because now I don't need to bring about so much cash and risk losing it)
So I suppose technology has reduced the chance of getting scammed, and increased passenger safety. But still, it makes the holiday experience somewhat "sterile".
What do you think?
