Ramming ... WTF?!, I must be reading this wrong Options

[Ayeohx]

Man, I sure hope I'm reading this crap wrong. The damage to passengers from ramming seems WAY over the top. I'm going to give a scenario using the rules that way I understand it. If I'm wrong please correct me.

From what I'm seeing, ramming happens anytime someone wants to drive their vehicle into someone else's, be it a head-on collision, a sideswipe or ramming into the rear of the vehicle, correct? Even it is ramming into the side the damage is insane.
.....
Scenario:

A team of runners hijack a bus (a Vista from the Arsenal book). The team is slowly rolling at 30 meters a turn due to traffic (I think this is about 22 mph, btw). They are running from a rival shadowrunner team in a GMC Hermes van. The Hermes van rams into the bus. This isn't a head-on collision, just a hard slam into the side while driving parallel. If this situation isn't a ram (let me know!) then assume that the Hermes is t-boning the bus.
The ram is successful, moving onto damage.

Stats:
Hermes Van - Rammer
Body 17
Armor 6
Speed 30 meters/round

Vista (Bus) - Rammee
Body 20
Armor 4
Speed 30 meters/round

Outcome:
The Vista bus, and everyone in it, must resist DV 17 (the Body of the Hermes).
The bus rolls 24 dice (Armor+Body). That's 6 auto successes. The bus takes 11 damage. It has 7 boxes left.

The soon to be dead guys in the bus roll their Body+ 1/2 Impact Armor + 4 (the bus's armor).
The troll enforcer, with a Body 9 + 3 from the Lined Coat & Natural Armor + 4 for the vehicle's armor, gets to roll 16 dice. He gets 4 hits and take 13 boxes. He's out and bleeding to death.
The hacker, the mage and the face fare even worse; the hacker dies instantly and the others are bleeding to death.
All are knocked unconscious and when they crash into the car in front of them they are die instantly.

The Hermes, and everyone in it, must resist DV 10 (1/2 the body of the Vista bus).
The Hermes rolls 23 dice. 5 auto successes. The Hermes takes 5 damage. It has 12 boxes left.

The Street Sam rolls 12 dice and gets 3 successes. He takes 7 damage. 5 boxes to go.
The hacker rolls 11 dice and gets 2 successes. He takes 8 damage. 2 boxes to go.

This can't be right. A 22 mph ram would never do this damage. Never ever. We had a truck with a snow plow tbone a school bus last year. No casualties; one kid in the hospital with a broken limb. Hell, my friend drove us into guard rail at around 20 mph (ice on the corner turn) and we dented the car. Oh, and no casualties (or airbag deployment, come to think of it... I shouldn't have bought that car).
