Challenges: 1. Keep the carriage's damage below 50%. 2. Hijack the carriage in less than 1 minute.
Your first objective is to infiltrate the Disraeli's carriage. This actually isn't too hard, despite the numerous cops crawling over the streets. Make a zipline to the house of the Disraeli's and look down. Two policemen patrol directly below you. Either wait for them to pass by the carriage, or double air assassinate them while they move next to the carriage. Infiltrating the carriage triggers a scene.
Afterwards you'll have to protect the carriage from incoming attacks. Quickly climb the pillars of the large nearby building to reach four snipers and eradicate them ASAP, perhaps defeating a few with some knife quick throws. Quickly head back down, for there are two more enemy waves coming up.
When you've fought off all Blighters, a scene plays and the Disraeli's carriage is hijacked. Quickly pursue it by hopping in the nearby vacant carriage and ride next to the Disraeli's carriage. Move to the roof, hop onto the other carriage and take the driver's seat by hijacking the vehicle. Do this within one minute to complete the challenge; reaching the roof of the other carriage is essential here. Now all you have to do is make it out of the red Blighter zones to safety.
