I guess a ramming test against the barrier will be about right, it hardens pretty instantly...
According to the rules (p198 core) every 10cm thickness 1m2 area has 12 condition boxes and it resists damage with 12D...if you deal more than 6 boxes (probably) you make a 1m hole per net 6 boxes (I think...I don't like the barrier rules much) which is going to slow you down fast as you need to get through at a bare minimum 5m of material...?!?
Again, that's a quick interpretation of the rules, if I've missed something obvious please shout!
To add insult to injury your windscreen is going to be pretty caked in freeze foam! Fancy driving blind? 
Yikes - opposition should always just open with this stuff!
I'll try to find some time with the books when I get home, see if I can reconcile the crazy barrier rules with the crazy vehicle rules with the foam rules (not sure if this stuff was designed with moving cars in mind!).
I was honestly thinking about zipping out quickly, rather than plowing...
First three questions that come to mind -
(1) no chance to evade all or part of this stuff when it comes down?
(2) the ramming rules generally stipulate whatever you hit the other guy with, you and your passengers have to soak half that damage. Understandable, but not sure how that applies to the idea of
plowing through this stuff. Maybe we take that damage on the first impact?
(3) Or is there even a second try if I don't get through five meters on the first go? If that is the damage per 10cm of this stuff, and they have delivered a sufficient volume to fill this parking area
(do we have a height? that will be crucial), then I have to break that barrier 50 times (for a one-meter hole, but actually I guess I'll need two)?
Hmmm - yeah, sorry fo the thinking-out-loud stream-of-consciousness post, but....
So basically, if the car is auto-caught, that is cool. Let me know and I won't bore everyone with a zillion die rolls, just start thinking about other options to deal with this.
If there is a vehicle maneuver or stunt that will let the car get free, a simplified test would probably save everyone time and avoid pages of arguments?
(I could use a parked car or something as a ramp and then jump over the sea of stuff - yeah, a tough test, but the rules give an example target number to the Transporter thing where he jumps the car and hooks the bomb attached to his undercarriage on a handy crane, so why not?)
Thoughts?
