What is with all these boxes. The long things are some kind of wand, right - "Entropic Shield!" And he kicks the horse into gear and it takes off at a dead run.

How do horses even work - shit, is he trying to trample them? 

One of the cops leaps out of the way. The other shouts but doesn't shoot, there are too many people in front.

They get back in the car and drive behind him; a galloping horse is very slow compared to a car. They'll shoot it if he gets close to other people but they'd rather wait for another car to block him off first, they don't want to risk killing him by gunshot or the horse throwing him, that is so much paperwork.

The horse won't throw him, it's a Mount, they're very well behaved. The Entropic Shield won't last long, so he's going to zigzag a bit to try to lose them.

A horse might be able to turn faster than a car (because it is being recklessly unsafe, wow, who trained that horse) but a car has three times the top speed and can always catch up. And they know the roads here, they're not in any danger of losing track of him.

The only concern is what he'll do trying to escape them, because he is not driving that horse in a remotely safe fashion and could easily hurt someone without even meaning to. "Stop or we shoot," they yell through the car's loudspeaker.

He's certainly not trying to run anybody over but he is willing to make this thing jump over bollards, he can't read "one way" signs, and he doesn't know what "stop or we shoot" means but even if he did it would not be reassuring.

They can't jump over bollards! This is a very unfair advantage of horses and they do not wish criminals to adopt this novel approach. To that end, they shoot the horse.

...they mostly miss, because they are moving (and braking before the bollards) and the horse is moving too, but one bullet hits it. 

They will go the long way around, then, and coordinate with the other police car over the radio to figure out where he is and try to corral him in.

The horse does not really like running with a bullet in it but Raimon doesn't want to change horses now, he doesn't have the knack of landing on a fresh one from midair after dismissing the previous one. It slows down and he takes a more circuitous route to compensate.

There are three cars circling around the area now and if he keeps riding one of them is very likely to spot him eventually; running horses aren't stealthy. 

Also, here's yet another person leaning out a second storey window and pointing a little box at him!

Will people STOP IT with the BOXES, what the HELL. He'll aim a Flare at them. It won't hurt them but it'll hopefully teach them better for next time they want to box someone.

Flare is a very effective deterrent against boxing! The person screams and falls back. It also makes it easy to spot Raimon from a distance for a moment.

A car with flashing lights on top blocks the the road two intersections ahead of him.

Then he'll just have to turn left at one of those intervening intersections!

They will do their best to catch up before he can turn again and lose them! The other two cars will race to get ahead of his new bearing and herd him from either side. They're not very good at coordinating this (there's a reason filmed car chases have a chopper and don't take place at night) but being much faster than he is gives them an advantage.

If he's not distracted, he might notice the smell of the sea.

Sure, the sea, might as well head that way.

Oh good! Boxing him up against the sea means he'll have one less direction to run in. 

When he reaches the seaside promenade-and-beach there's a police car waiting two or three streets away in either direction, and the third one has finally regained line of sight on him from behind.

Are there cars on the beach? No? The horse can go on to the beach.

...The men in the cars can go on the beach! With their weird wands and everything! He's not getting past them this time, they're telling the few bystanders to clear the fuck off and approaching him carefully and preparing to shoot the horse again. 

("You are under arrest! Get on the ground or we'll shoot again!", etc.)

Yes he is clear that they are in a shouty mood! "I don't fucking speak whatever that is! Leave me alone, bitches!" he snarls over his shoulder while he gallops down the sand. He'll go into the shallow water to have a way past the guys, they'll be able to hit the horse but they're on foot now and if he can get clear long enough he can summon a new one.

He's crazy and/or desperate. The water slows the horse down without getting him far enough from them. They could go into the water themselves if they had to, but in fact they can hit his horse from the edge of the sand as he tries to ride past them.

Pity about the horse, it was trained or something, but no horse can survive that many bullets at close range. Hopefully they won't hit his leg.

The horse goes poof. He goes flying. No time like the present to try casting Mount in midair and seeing if he can land it.

Nope. He hits the sand. The new horse is over there. He hauls himself onto it and kicks it into gear before channeling.

What the fuck.

They can still shoot the... new horse but it is Very Against Procedures to attack an unknown and desperate-seeming cape when noone is in immediate danger! Who knows what he can do besides create horses! 

They will trail him while they call it in. The cars can still drive along the beachfront, right, he can't actually get away by riding along the sand.

...the city stops following the bay in about two miles if he keeps going, but they think there's some rocks past that? Or something? They're really not used to thinking of maps in terms of passability for horses! Anyway it's not their concern now, if he leaves the city he will presumably not be able to menace random passersby anymore.

If they're not trying to rectangle him that suits him fine! Gallop gallop gallop.

After some minutes, a red blur flashes past him very quickly. Once it's a hundred feet behind him, it slows down and resolves into a man in tight red clothes. He's jogging after him, not even really running, but every movement is so unnaturally quick that he keeps up with the horse anyway.

Wow, hell of a Haste. "Do you by any chance speak Chelish, mister adventurer?"

He does not! And if he doesn't, then nobody at HQ does.

Other than maybe Miss Militia, who has an eidetic memory and never sleeps and has been known to read encyclopedic dictionaries when she's alone and really bored in the middle of the night. And Armsmaster, who is secretly (or not so secretly) a robot. But Velocity has the most affection for languages out of the real humans around here and he's never heard whatever that is.

But he knows quite a lot of languages he can try at the cape (temporary codename: Horseman), especially if you count the ones in which he only knows how to say he doesn't really know them!

This involves getting ahead of the horse, slowing down enough for his speech to be intelligible instead of quiet and squeaky like a mouse and then catching up again, over and over, but he's long since learned to be patient with the limitations of his power. He has nothing better to do anyway, he's officially tasked with 'keeping an eye on Horseman until backup arrives' and he can speed all the way up if Horseman does anything even slightly threatening and so the alternative is to be bored for the next subjective hour, because his stupid power won't let him carry a book or a phone or anything.

This guy is not rectangling Raimon or shooting at him. He can stay for now. With lots of suspicious looks.
