EntityFramework, Inherited Classes without Discriminator

Is it possible to use POCOs and EF to work with the following situation? I would like to have a Vehicles table, with some bool fields such as IsFast, IsVan, IsTruck, and then have a Vehicles class, with a FastVehicle, Van, Truck class that inherit from Vehicles class, without having their own tables, and without having a discriminator field?

Something like:

public class Vehicle
{
    public int Id {get; set;}
    public bool IsFast {get; set;}
    public bool IsTruck {get; set;}
    public bool IsVan {get; set;}
}

public class FastVehicle : Vehicle
{
    public FastVehicle(){
        IsFast = true;
    }
}

public class Van: Vehicle{
    public Van(){
        IsVan = true;
    }
}

public class Truck : Vehicle
{
    public Truck(){
        IsTruck = true;
    }
}

And then maybe in my DbContext have something like:

public virtual DbSet<Vehicle> Vehicles {get; set;}
public virtual DbSet<Van> Vans => (DbSet<Van>) Vehicles.Where(v => IsVan);
public virtual DbSet<Truck> Trucks => (DbSet<Truck>) Vehicles.Where(v => IsTruck);
public virtual DbSet<FastVehicle> FastVehicles => (DbSet<FastVehicle>) Vehicles.Where(v => IsFastVehicle);

Is something like this possible? Or is it a bad idea for some reason? How would I go about overriding OnModelCreating?
