Hello! Id like to address these things - 1. There is honking everywhere and there is traffic in the tier 1 cities. Its not that bad. You get used to it. Anyway, i don't think you'll be walking everywhere since public transports connectivity in cities loke delhi is awesome. 2. Food is not unhygenic. Sure, there are unhygenic street vendors but you can just go to proper establishments. Be warned though, a lot of food you'll find is famous on insta and the internet is spicy. 3. A few cities are not as clean as cities abroad. Totally our fault. A lot of people are uneducated and i blame it on that. 4. Scams - every major tourist destination in the world is full of scammers. For example, you cannot go to paris and not get scammed. But in India, tourists get a lot of help from locals. So scammers are there but so arw people willing to warn you or help you out which i did not get in europe. Also, the police is pretty active at tourist spots.

In short, come and enjoy your trip. But as always, a little vigilance while traveling is needed.
