I love Unicode. It does wonders for non-Romanized languages online and allows me to view websites in Chinese, Cyrillic, Arabic, Farsi, Japanese, Urdu, Greek, and Korean all without downloading special fonts like I used to have to do.
I'd also love to be driven in a motorcade, or drive in one as police cars block off all other traffic on the road. Tales of the presidential motorcades, from Johnson to Clinton.
